Encyclopedia is a television series created by HBO and the for-profit branch of the Children's Television Workshop (CTW) (now known as Sesame Workshop), Distinguished Productions, Inc. (DPI) (which has since been folded into Sesame Workshop). The series premiered on HBO in 1988.

Each episode covered a letter or series of letters in the alphabet, with short skits of sketch comedy devoted to up to twelve corresponding encyclopedia topics. Several topics were related through song. Three of the six writers of the show had also been writers for NBC's Saturday Night Live: Patricia Marx, Brian McConnachie, and Mitchell Kriegman.

The series featured the band BETTY, who performed both the opening and closing themes as well as individual songs for selected topics.
