Is It Illegal to Clone Humans? US Laws Explained 2026

Cloning a human being is effectively prohibited in the United States, though the legal picture is more complicated than a simple yes or no. No single federal law makes it a criminal offense nationwide, but a web of federal regulations, agency rules, and state statutes puts human cloning firmly off-limits.

Most people assume there is one clear federal ban. There is not. What exists instead is a patchwork system that has stopped every known attempt dead in its tracks.

This article breaks down exactly what the law says, which states have gone further than federal rules, what the penalties look like, and why the legal line between different types of cloning matters more than most people realize.

Is It Illegal to Clone Humans?

Yes, cloning a human being is effectively illegal in the United States under current federal regulations and state law. No laboratory, hospital, or private entity has legal permission to create a cloned human embryo intended for birth.

The Food and Drug Administration declared in 1998 that any attempt to clone a human being requires an Investigational New Drug (IND) application. No such application has ever been approved. That means any scientist or institution that tried to clone a human without FDA clearance would be violating federal regulatory law immediately.

On top of that, 15 states have passed their own statutes that explicitly criminalize human cloning. So depending on where you are in the US, you could face both federal regulatory violations and state criminal charges.

The short answer: yes, it is illegal. The longer answer is that the type of cloning, the purpose, and your state all determine exactly how illegal it is.

Quick Facts:

• FDA has blocked all human cloning attempts since 1998
• 15 states have passed explicit anti-cloning statutes
• No federal criminal penalty statute has passed Congress as of 2026
• Reproductive cloning faces the strictest prohibitions at every level

Is It Legal to Clone Humans?

No, cloning a human is not legal in the United States under any currently approved process. The distinction worth understanding is that “legal” and “criminal” are not always the same thing.

Reproductive human cloning (creating a cloned baby) has no legal pathway in the US. The FDA’s authority over biological products effectively blocks this at the federal level. States like Michigan, California, Arkansas, and Virginia have gone further by making it an explicit crime under state law.

Therapeutic cloning, which involves creating a cloned embryo to harvest stem cells rather than to produce a child, exists in a gray area in some states. A small number of states permit it under strict conditions for research purposes.

Think of it like jaywalking in some cities: technically against the rules everywhere, but the severity of what happens to you depends entirely on where you are standing when you do it.

What makes it “not legal” at the federal level:

• FDA regulatory block on unapproved biological procedures
• Congressional funding restrictions on cloning research
• National Institutes of Health (NIH) funding bans on certain embryo research
• Proposed federal criminal bills that have been debated repeatedly since 1997

Is Human Cloning Illegal in the US?

Human cloning is effectively illegal across the United States, but the mechanism of that illegality varies. At the federal level, the prohibition works through regulatory agencies rather than a criminal statute.

The FDA asserts jurisdiction over human cloning as a form of “biological product” development. Since 1998, the FDA has required prior approval for any cloning-related human research. No approval has ever been granted for reproductive human cloning.

Congress has attempted to pass explicit criminal bans multiple times. The Human Cloning Prohibition Act was introduced in various forms between 1997 and 2007. None of these versions passed the Senate, largely due to disagreements over whether to ban therapeutic cloning alongside reproductive cloning.

The gap between “no federal criminal law” and “completely illegal” confuses a lot of people. The answer is that regulatory law can stop something just as effectively as criminal law. You do not need a criminal statute if agencies have the power to halt every attempt before it starts.

Is Cloning a Human a Crime?

In at least 15 states, yes, cloning a human being is a crime with specific criminal penalties attached. At the federal level, it is not yet codified as a criminal offense in the US Code, but that does not mean someone could attempt it without legal consequences.

Michigan has the most aggressive criminal statute. Under Michigan Compiled Laws Section 333.16274 and related provisions, human cloning is a felony punishable by up to 10 years in prison and fines up to $10 million. Michigan’s law covers both reproductive and therapeutic cloning.

Arkansas, under Arkansas Code Annotated Section 20-16-1001 through 20-16-1004, bans human cloning and makes violations subject to civil penalties. California’s Health and Safety Code Section 24185 bans reproductive cloning while allowing therapeutic cloning under certain conditions.

States with explicit criminal or civil cloning prohibitions:

• Michigan: Felony, up to 10 years prison, up to $10 million fine
• Arkansas: Civil penalties, reproductive cloning banned
• California: Criminal ban on reproductive cloning; therapeutic cloning permitted under regulation
• Virginia: Prohibition under Code of Virginia Section 32.1-162.22
• Iowa, North Dakota, South Dakota, Indiana, Louisiana: Various civil and criminal penalties

Federal Law on Human Cloning

Federal law on human cloning operates primarily through agency regulation, not through a standalone criminal statute. The FDA is the key federal body with authority over human cloning research.

The FDA’s position, formally stated in a 1998 letter to researchers, is that cloning a human being constitutes a clinical investigation subject to federal oversight under 21 CFR Part 312. This requires submission of an Investigational New Drug application. The FDA has made clear it will not approve such an application for reproductive cloning.

Congress has also used federal funding as a tool. Appropriations legislation has repeatedly included riders prohibiting the use of federal funds for human cloning research. This does not make cloning a federal crime, but it cuts off the money that most research institutions depend on.

Key federal actions on human cloning:

The absence of a federal criminal statute is a real gap. It means federal prosecution would have to rely on other laws if someone actually attempted to clone a human, including fraud statutes, FDA violation penalties, or research misconduct provisions.

Human Cloning Prohibition Act

The Human Cloning Prohibition Act is the name given to several bills introduced in Congress between 1997 and 2007 that attempted to make human cloning a federal crime. None of them ever became law.

The core of the debate was this: should Congress ban only reproductive cloning (creating a cloned baby), or should it also ban therapeutic cloning (creating cloned embryos for stem cell research)? Anti-abortion legislators wanted both banned. Scientists and patient advocates opposed banning therapeutic cloning because of its medical research potential.

The House passed versions of the bill in 2001 and 2003. The Senate never did. The impasse has never been resolved as of 2026.

What the bills proposed:

• Criminal penalties of up to 10 years in federal prison
• Civil fines of at least $1 million or twice the gross gain from any violation
• Prohibition on importing or exporting cloned human embryos
• Coverage of both reproductive and therapeutic cloning in the most restrictive versions

The failure of these bills is why the US still relies on FDA regulation rather than criminal law to block human cloning. It is a legally unusual situation where something society broadly agrees is wrong does not have a matching criminal statute at the federal level.

Key Takeaway: The Human Cloning Prohibition Act was never enacted into law. Federal control over human cloning currently rests on FDA regulatory authority and funding restrictions, not on a criminal statute in the US Code.

States Where Human Cloning Is Illegal

Fifteen states have passed explicit laws addressing human cloning, and the penalties and scope of those laws vary significantly. Some ban all forms of cloning. Others only target reproductive cloning while leaving the door open for therapeutic research.

Michigan stands out as the strictest state in the country. Its laws ban both reproductive and therapeutic cloning and impose felony-level criminal penalties. Most other states focus their bans on reproductive cloning.

States without explicit cloning statutes are not open territory. The FDA’s federal regulatory authority still applies nationwide. A researcher in a state with no cloning law still cannot proceed without FDA approval.

Quick Facts:

• 15 states have enacted some form of anti-cloning law
• Michigan has the toughest criminal penalties of any state
• California permits therapeutic cloning under regulation while banning reproductive cloning
• All 50 states are subject to FDA regulatory oversight regardless of state law

Reproductive Cloning vs Therapeutic Cloning Laws

The legal distinction between reproductive cloning and therapeutic cloning is the single most important thing to understand about human cloning law. These two procedures use the same technique but have entirely different legal statuses.

Reproductive cloning means using somatic cell nuclear transfer (SCNT) to create a cloned embryo with the intent to implant it in a uterus and produce a live-born human being. This is what most people picture when they hear “human cloning.” It is prohibited under FDA regulations and banned outright in at least 15 states.

Therapeutic cloning means using SCNT to create a cloned embryo for the purpose of extracting stem cells for medical research. The embryo is never intended for implantation. This has a different legal status in several states and was the main sticking point in every failed federal bill.

California’s law is a good example of how states handle this split. Health and Safety Code Section 24185 bans reproductive cloning as a crime. But California simultaneously passed legislation in 2002 explicitly protecting the right to conduct therapeutic cloning research, and voters approved Proposition 71 in 2004, which funded stem cell research including therapeutic cloning.

Therapeutic Cloning Legal Status

Therapeutic cloning occupies a distinct legal space from reproductive cloning in US law. It is not broadly legal, but it is not universally criminalized either.

At the federal level, therapeutic cloning requires FDA oversight like any other human biological research. There is no federal criminal ban specifically targeting therapeutic cloning. The failed Human Cloning Prohibition Act bills that would have banned it never passed the Senate.

Several states have taken proactive steps to protect therapeutic cloning as a form of medical research. California, New Jersey, Connecticut, Maryland, Massachusetts, and Illinois have all passed legislation that either explicitly permits therapeutic cloning or funds stem cell research that includes it.

States with protective laws for therapeutic cloning:

• California: Explicitly protected under state law; $3 billion in voter-approved funding (Prop 71)
• New Jersey: New Jersey Stem Cell Research Bond Act supports therapeutic research
• Connecticut: State funding authorized for embryonic stem cell research
• Maryland: Research permitted under state bioethics guidelines
• Massachusetts: Permits therapeutic cloning for research purposes

On the other side, Michigan, Iowa, North Dakota, and several other states have specifically banned therapeutic cloning alongside reproductive cloning. In those states, the legal prohibition covers the entire technique regardless of the intended purpose.

Key Takeaway: Reproductive cloning is blocked everywhere in the US through FDA regulation and state law. Therapeutic cloning is legal for research in some states and banned entirely in others. The divide tracks almost perfectly with broader political debates about embryo research.

Penalties for Human Cloning

The penalties for human cloning depend on where the attempt happens and whether state criminal law applies. At the federal level, penalties would come through FDA violation provisions and potentially other statutes rather than a standalone criminal law.

Under FDA regulations, violating the IND requirement by conducting unapproved human research can result in civil penalties and injunctions that halt research. Criminal referrals for willful violations are possible under 21 U.S.C. Section 333, which covers criminal penalties for intentional violations of FDA regulations.

State-level penalties are more specific and in some cases severe.

Michigan’s penalty structure is the outlier. A $10 million fine is massive by any standard and is clearly designed as a deterrent for institutions rather than individuals. No private person could realistically pay that; it targets research facilities and corporations.

Quick Facts:

• Michigan has the highest financial penalty: up to $10 million per violation
• Federal penalties rely on FDA violation statutes rather than a specific cloning law
• Civil penalties can shut down research institutions even without criminal prosecution
• No person has been criminally sentenced for human cloning in the US as of 2026

What Would Happen if Someone Cloned a Human?

If someone successfully cloned a human being in the United States, the legal response would come from multiple directions simultaneously. The person, institution, and any funders involved would face immediate action.

First, the FDA would move to halt the research and could seek a federal injunction to stop any further work. The agency has authority under the Federal Food, Drug, and Cosmetic Act to act immediately against unapproved biological procedures.

Second, if the attempt occurred in a state with a criminal cloning statute, state prosecutors could bring felony charges. In Michigan, that means up to 10 years in prison and a $10 million fine. In Virginia, it would be a Class 6 felony.

Third, federal prosecutors could potentially pursue charges under existing fraud statutes, FDA criminal violation provisions, or other applicable federal law, even without a specific cloning criminal statute.

The cascade of consequences would likely include:

• Federal injunction halting all research at the institution
• Loss of all federal research funding (NIH, NSF, DARPA grants)
• State criminal prosecution where applicable
• Civil penalties from the FDA
• Loss of medical licenses for any physicians involved
• Institutional accreditation review

The cloned child itself would have full legal personhood under US law. Nothing in current law would treat a cloned human differently from any other person born in the United States.

Why Is Human Cloning Illegal?

Human cloning is treated as illegal primarily for three reasons: safety concerns, ethical objections grounded in human dignity, and the absence of any demonstrated medical benefit for the reproductive version.

The safety argument is concrete. Cloning experiments in animals produce high rates of genetic abnormalities, premature aging, immune deficiencies, and developmental failures. Dolly the sheep, cloned in 1996, developed arthritis and lung disease and was euthanized at age six, roughly half the normal lifespan for her breed. Applying that track record to human beings is a scientific non-starter.

The ethical argument draws from the idea that creating a human being as a copy of another person treats them as a product rather than a person. The National Bioethics Advisory Commission concluded in 1997 that reproductive human cloning was “morally unacceptable” given the current state of science.

The third reason is political and practical. Congress has never resolved the disagreement between those who want all cloning banned and those who want therapeutic cloning protected. That deadlock has kept a federal criminal statute off the books while leaving the FDA as the de facto gatekeeper.

Key Takeaway: Human cloning is effectively illegal because of overlapping safety science, ethical consensus, FDA regulatory authority, and state criminal statutes. The lack of a federal criminal law does not mean it is a legal gray area; it means the prohibition is enforced through a different mechanism.

Human Cloning and FDA Regulations

The FDA is the most consequential federal body in human cloning law. Its regulatory authority has done more to prevent human cloning in the US than any legislation passed by Congress.

The agency’s position is that human cloning constitutes a “clinical investigation” of a biological product under 21 CFR Part 312. Any attempt to clone a human requires the submission of an Investigational New Drug (IND) application before any human subject research can begin. The FDA has explicitly stated it would not approve such an application for reproductive cloning.

This regulatory framework gives the FDA power to halt cloning research at the planning stage. Institutions that receive federal funding, which includes virtually every major research hospital and university in the country, risk losing everything if they proceed without FDA clearance.

What FDA regulation covers:

• Any attempt to use SCNT to create a human embryo for implantation
• Clinical trials involving cloned biological materials derived from humans
• Import or use of cloned human biological products in US research
• Any research involving human subjects that has not received IND approval

The FDA’s 1998 assertion of jurisdiction was significant because it did not require new legislation. The agency interpreted its existing authority broadly enough to cover human cloning, giving regulators a tool to act even as Congress debated for years.

History of Human Cloning Laws

The history of human cloning law in the US begins with a sheep. When Dolly the sheep was announced in February 1997, the reaction from policymakers was immediate and alarmed.

President Clinton issued a moratorium on federal funding for human cloning research within days of Dolly’s announcement. He also directed the National Bioethics Advisory Commission to study the ethics of human cloning. Their 1997 report concluded reproductive cloning was morally unacceptable and called on Congress to pass a temporary ban.

Congress debated but never passed a federal criminal ban. The House passed the Human Cloning Prohibition Act in 2001 and again in 2003. The Senate never voted on it due to the therapeutic cloning dispute.

The history shows a pattern: broad agreement that reproductive cloning should be banned, persistent disagreement over therapeutic cloning, and a Congress that has never bridged the gap.

Countries Where Human Cloning Is Banned

The United States is not alone in restricting human cloning. Most developed nations have enacted explicit bans, often backed by criminal penalties that go further than current US federal law.

The UK bans reproductive cloning under the Human Reproductive Cloning Act 2001, with criminal penalties of up to 10 years in prison. The UK simultaneously permits therapeutic cloning under strict Human Fertilisation and Embryology Authority (HFEA) licensing.

France and Germany both ban all human cloning, including therapeutic cloning, under national bioethics laws. Germany’s Embryo Protection Act of 1990 predates Dolly and imposes criminal penalties for creating cloned human embryos for any purpose.

The 2005 United Nations Declaration on Human Cloning called on all member states to ban human cloning “incompatible with human dignity.” It was not a binding treaty, but 84 countries voted in favor, including the United States.

Key Takeaway: The US is behind most comparable nations in one specific way: it lacks a federal criminal statute against reproductive cloning. The FDA regulatory block fills the gap, but it is a regulatory mechanism rather than a criminal law.

Ethical and Legal Issues With Human Cloning

The ethical and legal arguments against human cloning are deeply connected, and understanding one helps explain the other.

The core ethical objection to reproductive cloning is about the dignity of the cloned person. Critics argue that creating a human being as a genetic copy of another living person treats them as a means to an end rather than as a person with their own identity. The President’s Council on Bioethics, established under President George W. Bush in 2001, articulated this position in detail in its 2002 report.

The legal issues flow from that ethical foundation. Policymakers who accept the dignity argument have pushed for total bans. Those who believe therapeutic cloning is morally acceptable because it does not create a person intended for birth have blocked comprehensive federal legislation.

The main legal disputes as of 2026:

• Whether a cloned embryo has legal personhood (no US court has ruled on this directly)
• Whether therapeutic cloning research should be federally funded
• Whether states can regulate cloning differently from the federal standard
• Whether the FDA has proper statutory authority to regulate cloning under existing law (never fully litigated)
• Whether importing research from countries with different cloning laws creates legal liability in the US

The tension between science, ethics, and law in this area has produced a legal framework that most legal scholars describe as incomplete. The FDA block is effective but it was never designed as a permanent solution to the cloning question. At some point, Congress will need to act, or the courts will.

Frequently Asked Questions

Is it illegal to clone humans in the United States right now?

Yes, cloning a human being is effectively prohibited in the United States right now.
The FDA blocks all attempts through regulatory law, and at least 15 states have enacted criminal or civil statutes against it.
No federal criminal statute specifically covering human cloning has passed Congress as of 2026, but the FDA’s regulatory authority functions as an equally powerful barrier.

What is the difference between reproductive cloning and therapeutic cloning legally?

Reproductive cloning means creating a cloned embryo intended to produce a live-born human being, and it is prohibited everywhere in the US.
Therapeutic cloning creates a cloned embryo to harvest stem cells for research, never for implantation, and it is legal in several states including California.
The legal distinction is the single biggest reason Congress has never passed a comprehensive federal cloning ban, as lawmakers cannot agree on whether the therapeutic version should be included.

Which states have made human cloning a crime?

At least 15 states have passed anti-cloning statutes, with Michigan, Virginia, Iowa, North Dakota, Indiana, Arkansas, California, Louisiana, and South Dakota among them.
Michigan has the most severe criminal penalties, including up to 10 years in prison and fines as high as $10 million.
States without explicit statutes are still covered by FDA regulatory requirements, so no state is a legal free zone for human cloning.

Has anyone ever been prosecuted for attempting to clone a human?

No one in the United States has been criminally prosecuted for attempting to clone a human being as of 2026.
In the early 2000s, several fringe groups including one associated with the Raelian religious movement claimed to have cloned humans, but no verified evidence ever supported those claims.
The FDA’s regulatory framework has been sufficient to prevent any serious attempt from advancing far enough to trigger criminal prosecution.

Is therapeutic cloning legal in any US state?

Yes, therapeutic cloning is explicitly permitted or protected by law in several states.
California, New Jersey, Connecticut, Maryland, Massachusetts, and Illinois have all passed legislation supporting therapeutic cloning or the stem cell research it enables.
At the federal level, there is no criminal ban on therapeutic cloning, though all research still requires FDA oversight and approved protocols.

The law around human cloning in the US is more layered than most people expect. There is no single “Human Cloning Is Illegal” statute in the federal code, but the combination of FDA regulatory power, state criminal laws, and funding restrictions has built a system that effectively prevents it.
