Bushido Blade (ブシドーブレード, Bushidō Burēdo) is a 3D fighting video game developed by Lightweight and published by Square and Sony Computer Entertainment for the PlayStation. The game features one-on-one armed combat. Its name refers to the Japanese warrior code of honor bushidō.

Upon its release, the realistic fighting engine in Bushido Blade was seen as innovative, particularly the game's unique Body Damage System. A direct sequel, Bushido Blade 2, was released on the PlayStation a year later. Another game with a related title and gameplay, Kengo: Master of Bushido, was also developed by Lightweight for the PlayStation 2.
