Ninetails is one of the bosses and main villains from the Capcom video game Okami. A demon fox that fancies itself as a god, it spends most of the story disguised as Priestess Rao, who it had murdered prior to the start of the game.

Ninetails takes the form of a massive, golden-yellow nine-tailed fox wearing a white and red mask. Each tail has a red brush tip, and eight tails have fox masks. It wields a sword with nine blades in combat. When Amaterasu destroys all but its central tail, Ninetails loses its mask and reverts to its true form, where it has ragged brown fur, a yellow left eye with red sclera, and is missing its right eye with a scar over the eyelid.

Ninetails's gender is ambiguous, and is referred to with both male and female terms throughout the game.
