Maisy is the star of the long-running series of children's picture books by acclaimed English children's author and illustrator Lucy Cousins. These books chronicle the adventures – from the day-to-day to the fantastical – of Maisy the mouse and her friends Cyril the squirrel, Tallulah the chick, Charley the crocodile and Eddie the elephant.

The series began in 1990 with the publication of Maisy's Bedtime, and has since gone on to sell 26.5 million copies around the world and has been translated into 26 different languages.

Adapted for an animated series in the US, this has also received an excellent response in Japan where it has been broadcast on NHK Educational and Cartoon Network.
