Wonderbeaver is a 2003 animated series produced by Nelvana and Act III Productions based off "It's the Wonderbeaver" by Brian Jacques and Phelan Morkel. The series' theme song was performed by British ska band Madness and was released as a single in 2004 by Virgin Records.

The series aired from October 4, 2003 to May 21, 2005 on Kids' WB. It has been rerun on Azteca América (dubbed in Spanish) and Range. The series ran for 65 episodes in it's first season and 33 episodes in it's second season, bringing the total number to 98.

Midway through Season 2, Wonderbeaver and her team, Wonderbeaver & Team Co. Thing, teamed up with characters from the Warriors novels by Erin Hunter and the show became Wonderbeaver and the Warriors. This was done to keep the rights for the characters after Nelvana's original attempt at an adaptation was cancelled by PBS Kids due to low ratings.
