Takeshi's Castle (Japanese: 風雲!たけし城, Hepburn: Fuun!Takeshi-jō) is a Japanese game show that aired between 1986 and 1990 on the Tokyo Broadcasting System (TBS). It features the Japanese comedian Takeshi Kitano (also known as Beat Takeshi) as a count who owns a castle and sets up difficult physical challenges for players (or a volunteer army) to get to him.

The show became a cult television hit around the world. It was highly influential on global popular culture, inspiring a genre of game shows involving physical challenges and painful entertainment, as well as other media. A special live "revival" was broadcast on 2 April 2005, for TBS's 50th anniversary celebrations. It was revived again in April 2023 for eight episodes which aired on Prime Video.
