Planet Prince is a 1958 tokusatsu superhero television series. Created by veteran writer Masaru Igami and produced by Nippon Gendai and Senkosha, the series aired on NTV from November 4, 1958 to October 6, 1959, with a total of 49 episodes. It was created to capitalize on the success of the Super Giant serials. In fact, the title hero bore a strong resemblance to Super Giant.

Toei produced two movies that featured the character, but in a completely different, more streamlined costume. The hero was this time played by Tatsuo Umemiya. The films were titled:

⁕Planet Prince Released: May 19, 1959

⁕Planet Prince - The Terrifying Spaceship Released: May 25, 1959

For release in America, these two movies were compiled into a TV movie titled Prince of Space.
