Chipmunks are related to squirrels. They belong to the rodent order Rodentia within the mammal class Mammalia.
Chipmunks are small striped members of the squirrel family Sciuridae. Their closest comparisons come from other squirrel groups and ground-dwelling relatives.

That family link explains why chipmunks share traits with squirrels, such as sharp incisors, nut gathering, and quick climbing. Chipmunks look different from many people’s idea of a squirrel because they are smaller, striped, and built for burrowing as much as climbing.
Where Chipmunks Fit In The Animal Family Tree

Chipmunks sit inside the sciuridae family, which is the larger squirrel family. They are one branch of squirrels, alongside other species that live in trees, on the ground, or glide.
Chipmunks As Members Of The Sciuridae Family
Scientists classify chipmunks as small striped squirrels in the family Sciuridae and the subtribe Tamiina. Their old common names include “striped squirrel” and “ground squirrel,” though the latter name refers to several different animals.
How Tamiina, Tamias, And Tamias Striatus Fit In
Researchers have split different chipmunk species among genera such as Tamias, Eutamias, and Neotamias. The eastern chipmunk is Tamias striatus, while the Siberian chipmunk belongs to a separate lineage.
Why Chipmunks Are Rodents And Also Squirrels
Chipmunks are rodents because they belong to Rodentia, the mammal order defined by gnawing teeth. They are also squirrels because Sciuridae is a rodent family, so both labels apply at different classification levels.
Which Animals Are Chipmunks Closest To
Chipmunks are most closely tied to other squirrel relatives, especially small ground-dwelling forms. Their closest comparisons vary, because tree-living, ground-living, and gliding squirrels split into different branches within the broader squirrel group.
Tree Squirrels, Ground Squirrels, And Flying Squirrels
Among tree squirrels, ground squirrels, and flying squirrels, chipmunks align more closely with the ground-dwelling side of the family. Ground squirrels and chipmunks often share body shape, habits, and habitat choices, while flying squirrels are more specialized for gliding.
How Chipmunks Compare With Eastern Gray Squirrels And Fox Squirrels
Eastern gray squirrels and fox squirrels are cousins, but they usually spend more time in trees and have a different build. Chipmunks are smaller, stay lower to the ground, and dash between logs, rocks, and burrow entrances rather than leaping through open canopies.
Why Prairie Dogs And Other Ground Squirrels Are More Distant Relatives
Prairie dogs and other ground squirrels share more ground-based traits with chipmunks than tree squirrels do. Even so, they are not the same kind of animal, and the family contains many different squirrel species with their own niches and behaviors.
Traits That Show Their Squirrel Connection
Chipmunks show their family ties in everyday habits, especially how they eat, store food, and build shelter. Their body plan and behavior make the link to squirrels easy to spot once you know what to look for.
Cheek Pouches, Foraging, And Food Storage
Chipmunks use cheek pouches to carry food while foraging, which is a classic squirrel-family trait. They gather seeds, nuts, fruits, and sometimes mushrooms, insects, worms, or bird eggs, then move them back to storage sites for later use.
Burrows, Tunnel Systems, And How They Differ From Dreys
Chipmunks dig burrows with elaborate tunnel systems instead of living in leafy dreys like many tree squirrels. That underground setup gives them safe places for nesting, food storage, and escape routes, which fits their ground-oriented habitat.
Diet, Hibernation, And Everyday Behavior
Chipmunk diet varies with season, but cached food matters a lot when winter arrives. Some species hibernate, and their active days include rapid movement, sharp chatter, and the familiar chuck call that makes them easy to notice in the wild.
Common Species, Habitat, And Survival In The Wild
Chipmunks live across different regions, and their species range helps explain why their habits vary. Their survival depends on habitat cover, food access, and staying alert around predators.
Eastern Chipmunk, Least Chipmunk, And Yellow-Pine Chipmunk
The eastern chipmunk, least chipmunk, and yellow-pine chipmunk are among the better-known species. The Siberian chipmunk stands out because its distribution extends into Asia, while most chipmunk species are centered in North America.
Where Chipmunks Live And How Their Habitat Shapes Behavior
Chipmunks favor forests, brushy edges, rocky slopes, and places with good cover and food. Their habitat shapes their behavior, since dense ground cover supports burrows, hiding spots, and quick trips between safe feeding areas.
Predators That Chipmunks Share With Other Small Squirrels
Many of the same predators hunt chipmunks and other small squirrels. Hawks, owls, foxes, raccoons, snakes, weasels, coyotes, bobcats, and lynx all pose risks.
Chipmunks rely on alertness, camouflage, and fast escapes to survive.
