This is a list of animals that have been domesticated by humans.

The list includes species or larger formal and informal zoological categories that include at least some domesticated individuals.

To be considered domesticated, a population of animals must have their behavior, life cycle, or physiology systemically altered as a result of being under humans control for many generations. (Please see the main article on domestication for more information.) Animals included in this list that do not fully meet this criterion are designated "captive-bred".

This list is organized by the original or primary purpose for which the animals were domesticated. Animals with more than one significant human use have been listed in more than one category.
