Double Dragon (Japanese: 双截龍ダブルドラゴン Hepburn: Daburu Doragon) is a 1987 beat 'em up video game developed by Technōs Japan and distributed in North America and Europe by Taito. The game is a spiritual and technological successor to Technos' earlier beat 'em up, Nekketsu Kōha Kunio-kun (released outside of Japan by Taito as Renegade), but introduced several additions such as two-player cooperative gameplay and the ability to arm oneself with an enemy's weapon after disarming them. Double Dragon is considered to be one of the first successful examples of the genre, resulting in the creation of two arcade sequels and several spinoffs, as well as inspiring other companies in creating their own beat 'em ups.
Originally an arcade game, home versions were released for the NES, Master System, Atari 2600, Atari 7800, Atari ST, Amiga, Amstrad CPC, Commodore 64, Game Boy, Genesis/Mega Drive and Atari Lynx, among other platforms during the series's height of popularity. A remake titled Double Dragon Advance was released for the Game Boy Advance in 2003.
