Double Dragon (ダブルドラゴン, Daburu Doragon^?) is a beat 'em up video game series initially developed by Technōs Japan and owned by Arc System Works. The series stars twin martial artists, Billy and Jimmy Lee, as they fight against various adversaries and rivals. Due to the popularity of the game series, an animated series and live-action film adaptation have also been produced.

The original Double Dragon by Technōs was first released as a coin-operated arcade game in 1987. A Nintendo Entertainment System version also produced by Technōs was released the following year, followed by a Game Boy version in 1990. Various licensed versions of the games were also produced by other developers for various gaming platforms such as the Master System, Atari 2600, Atari 7800, Genesis, and the Lynx. Versions of Double Dragon for home computers were also released as well. A Game Gear game titled Double Dragon also exists, but it is not another port of the original game. It is based on Streets of Rage instead, especially the main character, Billy Lee, who strongly resembles Axel Stone, the protagonist of Streets of Rage series.
