Rabbits and hares are closely related, but they are not the same animal. Both belong to the order Lagomorpha and the family Leporidae, yet they differ in the kinds of species they include, how their young are born, and the ways many of them respond to danger.
The simple difference
Hares are generally the species in the genus Lepus; that group includes jackrabbits as well as hares. “Rabbit” is used for other members of the same family. The names can be confusing because common names do not always reveal the scientific group: a jackrabbit is a hare, not a true rabbit.
What rabbits and hares have in common
Rabbits and hares are mammals in the order Lagomorpha, alongside pikas. They are not rodents, although the two groups are related within a broader mammal lineage. Both rabbits and hares are leporids, with long hind legs, long ears, and plant-based diets.

How young rabbits and hares differ
The most dependable difference is how the young are born. Baby hares are described as precocial: they arrive fully furred, with their eyes open, and can move soon after birth. Baby rabbits are altricial: they are born with little or no fur, their eyes closed, and need more time in a protected nest.
Where they tend to live
Many hares live in open places and rely on speed and alertness to escape danger. Many rabbits use dense vegetation, nests, or burrows for cover. These are useful patterns, not rules for identifying every species: habitats vary across the many members of the rabbit-and-hare family.
Appearance: useful clues, not a complete test
Hares are often larger than rabbits and may have longer legs and ears. Some species also have dark ear tips. But appearance alone is not enough for a confident identification, because size, coat color, and ear length vary among species and seasons.
A quick comparison
| Feature | Hares | Rabbits |
|---|---|---|
| Scientific grouping | Usually genus Lepus | Other rabbit groups within Leporidae |
| Young at birth | Typically furred, eyes open, and mobile | Typically less developed, eyes closed, and nest-dependent |
| Common escape pattern | Often rely on running in more open habitat | Often use dense cover, nests, or burrows |
| Well-known example | Snowshoe hare or jackrabbit | Cottontail or domestic rabbit |
The takeaway
Rabbits and hares are close relatives in the same family, but they are distinct groups. The clearest general clue is their young: hares are born ready to move, while rabbits are born more dependent on a protected nest.
