Crash Bandicoot Purple: Ripto's Rampage and Spyro Orange: The Cortex Conspiracy (released as Crash Bandicoot Fusion and Spyro Fusion in Europe) are two 2004 action games published by Vivendi Universal Games (VU Games) and developed by Vicarious Visions for the Game Boy Advance (GBA). The games are a crossover between the Crash Bandicoot and Spyro series, and are the fourth installments of each series made for the GBA. The story follows Crash Bandicoot and Spyro the Dragon as they team up and set out to thwart the alliance of their respective enemies Doctor Neo Cortex and Ripto. In a departure from the series' usual format, the gameplay of both titles is based heavily on minigames.

The crossover was proposed by VU Games, driven by the concept of bringing the two characters together for the first time. Crash Purple and Spyro Orange were respectively Vicarious Visions' fourth and first Crash and Spyro title, and were built on the largest cartridges the company had yet worked with. The games received mixed reviews upon release. Crash Purple was generally regarded as the stronger title due to its more varied and challenging minigames, though it was faulted for weak platforming, short length, and a lackluster trading card system. Spyro Orange was seen as a weaker, less engaging game, with less varied minigames, simplistic platforming, and a lack of difficulty.
