The Legend of the Mystical Ninja is a light-hearted action-adventure game for 1-2 players by Konami, and was released for the Super Nintendo Entertainment System in 1991. It is the first game in the Japanese video game series Ganbare Goemon to have a Western release.

It underwent several changes compared to its Japanese counterpart Ganbare Goemon: Yukihime Kyuushutsu Emaki. The protagonists were renamed for the Western release, and some content was altered to comply with Nintendo’s strict censorship policies at the time, such as the removal of certain characters and cutscenes.
