Animal roleplay is a form of roleplay where at least one participant plays the part of a non-human animal. As with most forms of roleplay, its uses include play and psychodrama. The activity is often referred to as petplay.

The origins of animal roleplay and petplay are probably various and diverse, again depending upon the participants involved. However, its origins are certainly influenced by costuming , fiction , myth and legend , roleplay and psychodrama in their various aspects.
