Onimusha (鬼武者^?, literally "Oni Warrior") is a series of video games by developer Capcom. The series makes use of the historic figures that shaped Japan's history, retelling their stories with supernatural elements. Most of the games are of the action-adventure game genre, a combination of third person combat and puzzle solving, where the protagonist wields the power of the Oni, enabling them to fight the Genma, the main enemy of the series. As of 2012, Onimusha is Capcom's sixth biggest franchise, behind the Resident Evil, Street Fighter, Mega Man, Monster Hunter, and Devil May Cry series.

The series originates in Yoshiki Okamoto's 1997 idea to create Sengoku Biohazard, a ninja version of Capcom's own 1996 Resident Evil (known as Biohazard in Japan), set in the Sengoku period and featuring a "ninja house" filled with booby traps, similar to the mansion from Resident Evil, where battles would be fought using swords and shuriken: "The house will contain hidden doors behind walls, ceilings that fall down to you, scrolls and ninja magic, and many other ninja techniques." The project was originally intended for the Nintendo 64's 64DD.
