A babyfur is a member of the furry fandom who enjoys roleplaying as younger characters. They may also be an Adult Baby and/or Diaper Lover (collectively known as AB/DLs), or is otherwise involved in Infantilism. There are many different types of furs in the babyfur community, each focusing on different aspects and roles. Like furry in general, babyfur culture involves a good amount of role-playing (either light or heavy), both online and in the real world.

The community has been growing more and more popular since the mid-to-late 90's. While the community itself is still part of the furry fandom as a whole, it is large enough to present sufficient leaders, politics and drama to give the community a nearly independent feel to it.

Role-playing babyfurs will most often take on the role of a furry character in his/her infancy or childhood. Common roleplaying themes include "cute" clothing (onesies, footy pajamas, overalls, diapers) and a child's environment such as a nursery or daycare center, complete with cribs, high chairs, and babyish decor. A few babyfurs lucky enough to afford the privacy and devotion will set up adult nurseries to role-play as children in real life. A sexual subset of this type of roleplaying is known as ageplay.
