Spirit Warriors is a BBC children's adventure series, broadcast on BBC Two, BBC HD and CBBC. It is the first British television drama series to have a predominantly East Asian cast.

Very loosely inspired by ancient Chinese myths and legends, the show follows Bo, her sister Jen, and fellow schoolchildren Vicky, Trix and Martin who, during a trip to a museum, are transported to a parallel spirit world. Once there, they find themselves transformed into Spirit Warriors, each with his or her own special spirit power. With the help of their mentor Shen, a dragon, they have to use their new-found skills to navigate the realms of Wood, Water, Earth and Fire and find twelve legendary spirit pieces before the evil warlord Li and his henchman Hwang can get their hands on them.

The series was created and written by Jo Ho and produced by Nick Pitt. The working title was Bo and the Spirit World. Jon East, who had previously won a BAFTA for the children's docu-drama That Summer Day, was the executive producer, and directed half of the episodes including the start and end of the series. Episodes 4 to 8 were directed by the Australian director Mat King.

The show has been picked up internationally by Norway, South Korea, New Zealand and Singapore.
