Double Dragon (ダブルドラゴン, ) is a classic beat 'em up video game series initially developed by Technos Japan Corporation, who also developed the Kunio-kun series (Renegade, Super Dodge Ball and River City Ransom).
The series stars twin brothers, Billy and Jimmy Lee, who are followers of a fictional martial art called Sōsetsuken (双截拳), as they fight against various adversaries and rivals. Double Dragon has had several sequels and has been ported to several different platforms. 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 Technos was first released as a coin-operated arcade game in 1987. A Nintendo Entertainment System version also produced by Technos 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.
Two Double Dragon sequels were released for the arcade: Double Dragon II: The Revenge in 1988 and Double Dragon 3: The Rosetta Stone in 1990. Like the original, Technos also produced versions of both for the NES in 1989 and 1991 respectively. A fourth game was released exclusively for the Super NES titled Super Double Dragon, which was the last game produced by the original team at Technos which retained the beat-'em-up gameplay of the original.
In 1994, Tradewest released Double Dragon V: The Shadow Falls for the Super NES and Genesis in North America and Europe, a competitive fighting game developed by Leland Interactive based on the Double Dragon animated TV series by Bohbot Entertainment. A Jaguar version was released by Telegames as well.
Another fighting game was produced by Technos, simply titled Double Dragon, was released for the Neo-Geo arcade and home console in 1995. A Neo-Geo CD version was also released, as well as a PlayStation version by Urban Plant. It was the last Double Dragon game produced by Technos before the company went out of business.

In most of the Double Dragon games, the player takes control of a martial artist named Billy Lee (who usually wears blue), or his elder twin brother Jimmy Lee (who usually wears red), as they fight off against various gang members thorough the streets of a city and various other locations. The gameplay in most of the games takes place in a pseudo 3D perspective like in Renegade and later beat-'em-ups, in which the player character can move in four directions but are always facing left or right. There are various techniques. The player can perform a variety of martial art techniques against their enemies, as well use melee weapons such as baseball bats and throwing knives normally obtained from enemies. In some installments, there are techniques that can be done in combination with another player.
According to the supplementary materials for some of the games, the fictional martial art style of Billy and Jimmy is named Sōsetsuken (双截拳, "Twin Intercepting Fists"), a nod to Bruce Lee's fighting method of Jeet Kune Do, also known as the "Way of the Intercepting Fist". Additionally, some of the enemy characters take their names from Enter the Dragon such as Williams and Rowper from the first game, as well as Bolo and Ohara in certain versions of Double Dragon II: The Revenge.
