Maisy is a British-American children's animated television series based on the book series by Lucy Cousins. It is narrated by Neil Morrissey and Brian Greene in the US version. In the United Kingdom, it was broadcast on CITV (also broadcast on Nick Jr. in 1999 .) In the United States, it aired on the Nick Jr. block of the Nickelodeon cable television network and on Noggin (now Nick Jr.) The series was produced by King Rollo Films and PolyGram Visual Programming and later as Universal Pictures Visual Programming when PolyGram folded into Universal, when the company itself was bought by beverage brand, Seagram. Select General Motors vehicles sold throughout 2003 included entertainment systems preloaded with Nickelodeon content, including episodes of Maisy and fellow Noggin program Little Bear. Maisy reruns were aired on the Nick Jr. channel from 2009 until 2010. Maisy also appeared in several issues of Nick Jr. Family Magazine and Nick Jr. Noodle, even a few episodes long after the show ended production like the July/August 2008 issue.

It uses a reggae-influenced theme song and voice characterizations and sound effects by The Umbilical Brothers.
