Bananas in Pyjamas is an Australian children's television series that first aired on 20 July 1992 on ABC. It has since been syndicated in many countries and dubbed into other languages. In the United States, the "Pyjamas" in the title was modified to reflect the American spelling pajamas. It aired in syndication from 1995 to 1997 as a half-hour series, then became a 15-minute show paired with a short-lived 15-minute series The Crayon Box, under a 30-minute block produced by Sachs Family Entertainment titled Bananas in Pajamas & The Crayon Box. Additionally, the characters and a scene from the show were featured in the Kids for Character sequel titled Kids for Character: Choices Count. The pilot episode was Pink Mug.

The concept was inspired by the success of the song Bananas in Pyjamas, written by Carey Blyton in 1967, on Play School. This song, which had become a regular item on Play School, became the theme of the new series. The series was revamped in May 2011 as a CGI animated series created by Southern Star Entertainment.
