Non-human electoral candidates have been found in a number of countries. Often, the candidacies are a means of casting a protest vote or satirizing the political system. At other times it is simply done for entertainment value.

Electoral regulations may explicitly require candidates to be human (or equivalent wording), or they may require candidates to do things which animals cannot reasonably do (such as sign their names legibly on legal forms); most constituencies require candidates to be of the age of a legal adult, which eliminates many animals whose life expectancies usually make them too young to ever qualify. On some occasions, however, animals have been accepted as candidates, and they have even won office.
