Clockwork Knight is a 1994 platform game developed and published by Sega for the Sega Saturn. It was released in Japan on December 9, 1994, and as a launch title in North America and Europe, on May 11 and July 8, 1995, respectively. It was followed by Clockwork Knight 2.

On December 15, 1995, Clockwork Knight: Pepperouchau no Fukubukuro, a compilation featuring both Clockwork Knight titles and additional content was released in Japan. This version was used as the basis for the American release of Clockwork Knight 2, which was released on February 17, 1996, although with the first game locked behind a cheat code. Reviews were mixed, with critics praising the advanced graphics but criticizing the low difficulty, short length, and lack of gameplay innovation.
