Ever spot a tiny, striped critter zipping around your yard and wonder what it actually is? Yep, that’s probably a chipmunk—and to answer the obvious question, yes, chipmunks are rodents. They belong to the squirrel family. They’ve got the signature sharp teeth that never stop growing, and they’re always on the hunt for seeds, nuts, and sometimes even a stray insect or two.
Knowing that chipmunks are rodents actually makes it easier to understand why they act the way they do. They dig burrows like little pros and pack their cheeks full of food to stash away for later. If you’ve ever wondered what sets chipmunks apart from other rodents, or how they fit into the bigger animal picture, let’s dig a little deeper into these quirky forest dwellers.
Is a Chipmunk a Rodent?
You’ll usually spot chipmunks darting around forests or backyards, their stripes making them easy to recognize. They’ve got a lot in common with other small mammals, but there’s something about chipmunks that stands out.
Understanding where chipmunks fit in the animal world can help you see what makes them unique.
Rodent Family Classification
Chipmunks sit comfortably in the Rodentia family tree, right alongside rats, mice, and hamsters. All rodents share a set of super-strong front teeth—incisors—that never stop growing. Chipmunks definitely have those, and they use them for all sorts of gnawing and nibbling.
Rodents make up one of the biggest mammal orders out there, so chipmunks have a lot of distant cousins. You’ll notice chipmunks love to gnaw and stash food, classic rodent moves. That’s why scientists group them with other rodents.
Relation to Squirrels
Chipmunks belong to the squirrel family, called Sciuridae. So, they’re actually close relatives of both tree squirrels and ground squirrels. Both chipmunks and squirrels have bushy tails and share a serious love of nuts.
Squirrels usually stick to the trees, but chipmunks spend most of their time on the ground. Those bold stripes on a chipmunk’s back? Squirrels don’t really have those. And while both have cheek pouches, chipmunks seem to use theirs even more for hauling food. This family connection explains a lot about how chipmunks act and look.
Key Differences from Rats and Hamsters
Even though chipmunks, rats, and hamsters all count as rodents, you can spot the differences pretty quickly. Chipmunks are smaller than rats and have those eye-catching stripes, while rats are just plain and a bit longer.
Hamsters and chipmunks both have short bodies, but hamsters tend to stay hidden in burrows and come out at night. Chipmunks, on the other hand, are busy during the day and prefer forests or gardens. Chipmunks have bushy tails; hamsters barely have tails at all.
Here’s a quick rundown:
| Feature | Chipmunk | Rat | Hamster |
|---|---|---|---|
| Size | Small (5-6 inches) | Larger | Small |
| Stripes | Yes, on back | No | No |
| Activity Time | Daytime | Mostly night | Mostly night |
| Habitat | Forests, gardens | Urban, varied | Burrows, cages |
This makes it a bit easier to tell who’s who if you spot them outside or in someone’s home.

Chipmunk Species, Habitats, and Behavior
Chipmunks are small, busy rodents with some pretty interesting habits. You’ll find different types scattered from deep woods to suburban backyards.
Their behaviors can change a bit depending on where they live and what food is around.
Major Species: Eastern Chipmunk and Least Chipmunk
The Eastern chipmunk (Tamias striatus) is probably the one most folks picture. It’s the biggest chipmunk species, measuring about 14–19 cm long, with a reddish-brown coat and five dark stripes. You’ll mostly see these guys in eastern North American woodlands. They tip the scales at 70–142 grams.
The Least chipmunk, true to its name, is a lot smaller—almost half the size of the Eastern one. It’s common out west and sports similar stripes but a lighter body. Both types love to stuff nuts and seeds into their cheeks to carry home.
Comparison with Ground and Tree Squirrels
Chipmunks and squirrels are related, but their habits aren’t quite the same. Ground squirrels spend most of their time in open fields or grasslands. Tree squirrels, as you’d expect, stick to the treetops.
Chipmunks? They’re flexible. They run along the ground but can climb trees if they need to.
Flying squirrels can glide from tree to tree, but chipmunks don’t have that trick. Marmots and prairie dogs are bigger and like to hang out in groups, while chipmunks are smaller and mostly go solo.
Their burrows can get pretty complex, but chipmunks don’t live in big colonies.
Typical Habitats and Range
You’ll find chipmunks in a surprising range of places. They live in forests with lots of trees and shrubs, rocky spots, and even mountain meadows.
Eastern chipmunks like deciduous forests, while others do fine in dry scrub or up in the mountains.
Most chipmunks call North America home, but the Siberian chipmunk lives in Russia and parts of Asia. They dig tunnels underground, hiding the entrances with leaves or rocks.
Chipmunks adapt easily to spots with good hiding places and plenty of food.
Chipmunks in Gardens and Around Bird Feeders
Got a garden or a bird feeder? Chances are, chipmunks will show up now and then.
They love the seeds, nuts, and fruits you leave out. If you want to protect your plants, try putting up barriers like hardware cloth.
Chipmunks sometimes build nests near gardens, especially if there’s enough shelter around. You could attract them by planting shrubs or tossing down some natural ground cover, but think twice—these little guys will happily steal birdseed.
Managing chipmunk visits isn’t too complicated, but it takes some balance between changing up their habitat and being smart about how you feed the birds.
