The Black Ninja is a 2003 American martial arts action film written, directed and starring Clayton Prince, and featuring Carla Brothers, Nicky DeMatteo, Yuki Matsuzaki, Heather Hunter, John Canada Terrell and Michael Chance.

While protecting this young woman, he is confronted by The Red Ninja, a Japanese assassin, who years before killed his family rather than pay Ali for defending him.

Primarily financed by Clayton Prince, filming began in Philadelphia, Pennsylvania and ended after two weeks.

The Black Ninja was given a limited theatrical release on November 2, 2002, and distributed worldwide on DVD on January 14, 2003.

The film was heavily criticized for its apparent lack of martial arts choreography and generally poor quality of the story, acting and cinematography.
