Phantom Fighter, known in Japan as Reigen Doushi (霊幻道士?), is an action game developed for the Famicom by Marionette, and published in Japan by Pony Canyon in 1988. It was later published in the US for the NES by FCI in April 1990.

As a kung-fu master, the player must fight through eight towns filled with undead creatures known as Kyonshi in Japan (or Jiangshi in China), each with a unique town boss. A small selection of items, and a large number of fighting moves could be used on the enemy. The game also included a hidden character that made the game much more difficult, a baby kyonshi or "Conshi." An infinite amount of continues are available to complete the game.
