The Secret of Mulan is 1998 direct-to-video animated film. It is the 1998 entry in the series of "Secret of..." films released direct to video by UAV/Sterling Entertainment Group, which generally were adaptations of popular theatrical animated films released in a given year, such as The Secret of Anastasia and The Secret of the Hunchback. This film, written by Katherine Lawrence and Christy Marx, is based on the poem about Hua Mulan, which had been made as a film by Walt Disney Feature Animation the same year as Mulan, and combined with elements from another popular 1998 animated film from Pixar Animation Studios, A Bug's Life. The film is one of the early collaborations of the composer-lyricist team of Megan Cavallari and David Goldsmith, and some copies were released with a CD soundtrack attached to the back cover.
