A deer is a even-toed ungulate mammal in the family Cervidae.^[1] They form the family Cervidae. The word 'deer' is both singular and plural.

A male deer is called a stag or buck, a female deer is called a hind or doe, and a young deer is called a fawn, kid or calf.

There are about 60 species of deer. They originally lived in the Northern Hemisphere,^[2] and now are native to Europe, Asia, North America and South America. Humans have introduced deer to places where they did not live naturally, such as Australia, New Zealand, Hawaii and South Africa.
