Battletoads/Double Dragon, also known as Battletoads/Double Dragon: The Ultimate Team, is a 1993 beat 'em up game developed by Rare and published by Tradewest. It was originally released for the Nintendo Entertainment System and later ported to the Sega Mega Drive/Genesis, Super NES, and Game Boy. It is a crossover of both Technōs Japan's Double Dragon and Rare's own Battletoads game franchises, although Technōs had little or no credited involvement in the production of the game outside of the Double Dragon license. The game's engine and design are directly based upon the Battletoads series.

The game features the Battletoads, the three humanoid amphibian protagonists from the eponymous franchise, as well as the protagonists of the Double Dragon series, Billy and Jimmy Lee, two young martial arts experts. It is also the first Battletoads game to feature all three 'Toads as playable characters.
