有蹄类是指几类使用趾尖（一般都有蹄）来支撑身体的哺乳动物。牠们共有几个目，当中有6-8个仍然生存。就有蹄超目是一个支序分类学的分支，或只是一个分类单元仍存有争议，因为未必所有有蹄类都是彼此近亲的。有蹄类过往被认为是一个目，及后分裂成奇蹄目、偶蹄目、管齿目、蹄兔目、海牛目及长鼻目。奇蹄目、偶蹄目及鲸目被称为「真有蹄类」，而长鼻目、海牛目、蹄兔目及管齿目则合称为「准有蹄类」或「近蹄类」。

现今普遍的有蹄类有马、斑马、驴、牛、犀牛、骆驼、河马、山羊、猪、绵羊、长颈鹿、鹿、貘、羚羊及瞪羚。

Ungulates (pronounced /ˈʌŋɡjᵿleɪts/) are any members of a diverse clade of primarily large mammals that includes odd-toed ungulates such as horses and rhinoceroses, and even-toed ungulates such as cattle, pigs, giraffes, camels, deer, and hippopotamuses. Most terrestrial ungulates use the tips of their toes, usually hoofed, to sustain their whole body weight while moving. The term means, roughly, "being hoofed" or "hoofed animal". As a descriptive term, "ungulate" normally excludes cetaceans (whales, dolphins, porpoises), as they do not possess most of the typical morphological characteristics of ungulates, but recent discoveries indicate that they are descended from early artiodactyls. Ungulates are typically herbivorous (though some species are omnivorous, such as pigs), and many employ specialized gut bacteria to allow them to digest cellulose, as in the case of ruminants. They inhabit a wide range of habitats, from jungles to plains to rivers.
