If you’ve gone down the pet monkey rabbit hole on social media and started wondering whether you could actually keep one in Ohio, the short answer is that it depends on the species.

Ohio has some pretty strict rules when it comes to keeping primates as pets, but it’s not a complete ban.

A small number of primate species are legal to own, as long as you meet the state’s requirements and register them properly. But for many other species, private ownership simply isn’t allowed.

So before you get too attached to the idea of having a monkey at home, here’s what you need to know about Ohio’s rules.

Ohio’s exotic animal laws weren’t always this strict. Before 2012, Ohio was actually one of the easier states in the country for people to own animals like lions, tigers, bears, and monkeys with relatively little oversight.

That changed dramatically after an incident in Zanesville in October 2011, when an exotic animal owner released nearly 50 wild animals from his property before taking his own life. Tigers, lions, bears, wolves, and primates ended up roaming the area, and local law enforcement had to kill most of the animals to protect the public.

The incident made international headlines and became a major example of why stronger exotic animal laws were needed.

In response, the Ohio Governor signed the Dangerous Wild Animal Act (Ohio Revised Code Chapter 935) into law on June 5, 2012.

The law was fully enforced beginning January 1, 2014 and it dramatically changed the rules around which exotic animals Ohio residents could legally own.

Under Ohio’s exotic animal law, most nonhuman primates are classified as dangerous wild animals.

The law specifically excludes lemurs and then separately names a number of other primate species that are also regulated as dangerous wild animals.

So don’t assume that a small primate or commonly kept monkey is automatically legal just because it’s smaller or less intimidating.

The Primates You Can Legally Keep

Ohio has a specific registration provision for a limited group of primates:

• Lemurs

• Squirrel monkeys

• Certain marmosets: pygmy, white tufted ear, silvery, and black pencilled marmosets

• Certain capuchins: brown, white faced, weeping, and white fronted capuchins

That doesn’t mean you can simply buy one and keep it like a dog or cat, though. Ohio also has rules covering registration, identification, care, and housing, and local laws may impose additional restrictions.

What About Other Monkeys?

Most other primates are classified as dangerous wild animals under Ohio law.

The list includes species such as macaques, baboons, spider monkeys, howler monkeys, woolly monkeys, tamarins, titi monkeys, night monkeys, great apes, and several others.

For dangerous wild animals, Ohio prohibits private possession unless the person or organization falls under a specific exception or has the appropriate authorization under Chapter 935.

Approved exceptions include zoos, research facilities, wildlife sanctuaries, rescue facilities, and holders of specific state permits (not for pet ownership).

Ohio law also provides narrowly defined exceptions for certain primates that are trained to assist people with disabilities.

So if you’re looking at a particular monkey species, don’t rely on a general “monkeys are legal in Ohio” list. The exact species matters, and so does the type of authorization and the circumstances under which the animal would be kept.

If you’re set on one of the primate species Ohio allows, ownership still isn’t as simple as buying your monkey and bringing it home.

Ohio requires registration with the Ohio Department of Agriculture, and the registration process includes providing detailed information about both you and the animal.

Depending on the animal and the applicable requirements, you may need to:

• Complete the state’s registration paperwork with information about yourself and where the animal will be kept.

• Provide detailed identification information about the animal, including its species, sex, age, color, weight, and distinguishing features.

• Have the animal permanently microchipped as part of the registration process.

• Follow state requirements for care and housing that apply to registered animals.

• Keep your registration information current and comply with any applicable reporting or regulatory requirements.

This means registration isn’t just a one time formality—keeping a pet monkey legally means staying on top of Ohio’s requirements for as long as you have it.

This is the part that’s easy to overlook! Even if a particular primate can be registered under Ohio law, your city or county may have its own rules that are more restrictive. 

Some local governments prohibit or limit private primate ownership regardless of what state law allows.

Before you get too attached to the idea, check with your local zoning or animal control office and ask whether keeping a primate is allowed where you live.

It’s much better to find out before bringing an animal home than after the fact.

Possessing a dangerous wild animal without the proper authorization in Ohio is a serious matter—it’s not simply a slap on the wrist violation.

Depending on the specific offense, violations can lead to criminal charges and civil fines, with penalties becoming more serious for repeat violations.

Ohio’s rules also give the state authority to investigate unauthorized possession and, in certain circumstances, order an animal to be transferred to an approved facility or euthanized.

There’s also a practical risk that’s easy to overlook. If you’re keeping an exotic animal illegally or aren’t meeting the state’s requirements, you could eventually lose the animal. And once you’ve bonded with a pet, having it taken away and moved somewhere else can be incredibly difficult.

That’s why it’s worth making sure you can meet all of the legal requirements before bringing your monkey home.

Ohio’s rules aren’t necessarily the only ones you need to think about. Federal laws can also come into play, especially if you’re buying or transporting a monkey across state lines.

Depending on the species and where the animal is coming from, federal rules such as the Captive Wildlife Safety Act and CITES may affect whether the animal can be sold, transported, or imported.

So even if Ohio allows you to keep a particular species, that doesn’t automatically mean you can legally buy one from a breeder in another state and bring it home.

If you’re considering an out of state purchase, check the federal requirements and make sure the breeder can legally complete the transaction before making any arrangements.

It’s much easier to sort out the paperwork beforehand than to discover there’s a problem after you’ve already bought the animal.

Ohio isn’t a state where you can casually decide to get a pet monkey. The rules are strict, and while a limited number of primate species may be kept with the proper registration, many others are off-limits to private owners.

If you’re seriously considering getting a pet monkey, start by checking Ohio’s current registration requirements for the specific species you’re interested in. Then check with your city or county before making any plans or paying a breeder.

It may not be the answer you were hoping for, but finding out that your local rules say no is a lot better than discovering it after you’ve already fallen in love with the idea (or the animal).
