Brave Fencer Musashi (ブレイヴフェンサー 武蔵伝, Bureivu Fensā Musashiden, "Brave Fencer: The Legend of Musashi") is an action role-playing video game developed and published by Square in 1998 for the PlayStation home console. The game involves real-time sword-based combat in a 3D environment; it also features segments of voiced over dialogue and role-playing game elements such as a day-night cycle and resting to restore energy.

The story follows Musashi, a young swordsman is summoned to a parallel world to defend the Allucaneet Kingdom from the Thirstquencher Empire. He searches for the Five Scrolls, which can enhance the powers of his sword, while interacting with people from Allucaneet and a nearby village.

Development began in early 1997, and was directed by Yoichi Yoshimoto, produced by Yusuke Hirata, and scored by Tsuyoshi Sekito. The game was a departure from Square's previous role-playing video games, which brought the team several difficulties during development. The game received a positive critical response; reviewers praised the graphics in comparison to other similar games of the time, and found the gameplay, especially the action elements, very compelling. Musashi received a sequel in 2005 for the PlayStation 2 under the name of Musashi: Samurai Legend.
