Double Dragon (双截龍, Daburu Doragon - Sō Setsu Ryū) is a beat 'em up video game series initially developed by Technōs Japan and released as an arcade game in 1987. The series features twin martial artists, Billy and Jimmy Lee, as they fight against various adversaries and rivals.

The original Double Dragon was a blockbuster hit arcade game, ushering in a "Golden Age" for the beat 'em up genre, resulting in a flood of beat 'em ups during the late 1980s to 1990s that followed the conventions set by Double Dragon. Due to the popularity of the game series, a 1993 animated series and 1994 live-action film adaptation were produced; these adaptations were widely-panned by critics and audiences.

The franchise is now the property of Arc System Works, the company that ported the original Double Dragon to the Sega Master System console in 1988.
