Tekken (Japanese: 鉄拳?, "Iron Fist") is a fighting game franchise created, developed and published by Namco (later Namco Bandai Games). Beginning with the original Tekken in 1994, the series has received several sequels as well as updates and spin-off titles, as well as three films and other media. The series' official English name is always written in all-capital letters (TEKKEN, abbreviated to TK).

The story in each game in the main series documents the events of the fictional martial arts tournament, the King of Iron Fist Tournament, hosted by the Mishima Zaibatsu corporation. The prize is typically control of the company, which then allows the winner to host the following tournament.

Tekken's main rivals have been fellow 3D-fighter series Dead or Alive and Virtua Fighter.
