Dead or Alive Ultimate (Japanese: デッドオアアライブアルティメット, Hepburn: Deddo oa Araibu Arutimetto, abbreviated as DOAU) is a compilation of fighting games developed by Team Ninja and released by Tecmo for the Xbox in 2004. It is a collection of the two previous games in the series, 1996's Dead or Alive and 1999's Dead or Alive 2. It marks the first game in the series to be a compilation. DOA Ultimate contains a high-resolution edition of the Sega Saturn version of Dead or Alive, and an enhanced remake of Dead or Alive 2 which utilizes a new graphics engine and offers Dead or Alive 3 game mechanics, new game content, and the inclusion of Hitomi as a playable character. The game offered online multiplayer capabilities, making the compilation among the first fighting games to offer online play.

Ultimate received generally favorable reviews from critics who praised the games' online functionalities. In 2006, both games became backwards compatible on Xbox 360.^[1] In 2021, both games were made available to download on Xbox Live worldwide, and were later added to the list of backward compatible games on Xbox One and Xbox Series X/S.^[2]
