Maisy is a preschool animated children's television series based on the book series of the same name by Lucy Cousins. The series aired from 11 February 1999 to 2 November 2000 on CITV and consisted of 26 episodes, with each episode being made up of four segments. It won the British Academy Children's Award for Pre-School Animation in 2000.
The show focuses on the lives of Maisy Mouse and all her friends. A mellow-voiced narrator narrates the action and communicates with the characters while the animals go through their paces communicating through unusual noises rather than traditional language. The characters are all meant to be between four and nine years old. The male narrator, however, can understand them easily because he is the only one who actually speaks. The animated series keeps the two-dimensional visual style of the books.
The show ran for one series of 26 episodes, with each episode consisting of four segments.
Maisy first aired on CITV in the United Kingdom from 11 February 1999 to 2 November 2000, with repeats airing until the mid-2000s.
In the US, the series aired on the Nick Jr. block on Nickelodeon from 1999 to 2000, with repeats airing on Noggin from 2001 to 2007 and on Qubo from 2008 to 2012.
Maisy won the British Academy Children's Award for Pre-School Animation in 2000.
In January 2024, it was announced that a new Maisy series, entitled My Friend Maisy, was put into development at Trustbridge Entertainment, with 52 five-minute episodes planned for the series. No date or broadcaster was announced for the project. In September, it was announced that the company would co-produce the series with BBC Studios Kids & Family and that A Productions and Karrot would handle animation production.
