The goat or domestic goat is a species of domesticated goat-antelope that is mostly kept as livestock. It was domesticated from the bezoar ibex of Southwest Asia and Eastern Europe. The goat is a member of the family Bovidae, meaning it is closely related to the sheep. There are over 300 distinct breeds of goat. It is one of the oldest domesticated species of animal - according to archaeological evidence its earliest domestication occurred in Iran at 10,000 calibrated calendar years ago.

The subfamily Caprinae, also sometimes referred to as the tribe Caprini, is part of the ruminant family Bovidae, and consists of mostly medium-sized bovids. A member of this subfamily is called a caprine.
