Crash Bandicoot is a video game series created by Naughty Dog and owned and published by Activision. The main games in the series are 3D platform games that follow the adventures of Crash, a human-like bandicoot, and his friends as they stop the plans of the mad scientist Doctor Neo Cortex and his helpers. The series began with the 1996 release of Crash Bandicoot, which became an important game for the PlayStation console. It was followed by two sequels from Naughty Dog: Crash Bandicoot 2: Cortex Strikes Back in 1997 and Crash Bandicoot: Warped in 1998. These games were originally made for the PlayStation, and later games appeared on Microsoft and Nintendo systems. After Naughty Dog left the series, other studios created mainline games, including Crash Bandicoot: The Wrath of Cortex (2001) and Crash Twinsanity (2004) by Traveller's Tales, as well as Crash of the Titans (2007) and Crash: Mind over Mutant (2008) by Radical Entertainment. A sequel to the original trilogy, Crash Bandicoot 4: It's About Time, was developed by Toys for Bob and released in 2020. Another sequel by Toys for Bob was cancelled in 2024 partly because Crash Bandicoot 4: It's About Time did not sell well enough.

In addition to platform games, the series includes kart racing games, party games, crossover titles, and mobile versions. Over the years, many studios have worked on the series, including Naughty Dog, Eurocom, Traveller's Tales, Vicarious Visions, Radical Entertainment, Beenox, and Toys for Bob. By 2007, the Crash Bandicoot series had sold more than 40 million copies worldwide. Since then, the series has continued to be successful, with Crash Bandicoot N. Sane Trilogy selling 20 million copies and Crash Team Racing Nitro-Fueled selling 10 million copies.
