Naughty Dog, LLC formerly JAM Software, Inc. is an American first-party video game developer based in Santa Monica, California. Founded by Andy Gavin and Jason Rubin in 1984, the studio was acquired by Sony Computer Entertainment in 2001. Gavin and Rubin produced a sequence of progressively more successful games, including Rings of Power and Way of the Warrior in the early 1990s. The latter game prompted Universal Interactive Studios to sign the duo to a three-title contract and fund the expansion of the company.

After designer and producer Mark Cerny convinced Naughty Dog to create a character-based platform game that would use the 3D capabilities of the new systems, Naughty Dog created Crash Bandicoot for the PlayStation in 1996. Naughty Dog developed three Crash Bandicoot games over the next several years. After developing Crash Team Racing, the company began working on Jak and Daxter: The Precursor Legacy for the PlayStation 2.

In 2004, Rubin, who had become the company's president, left the company to work on a new project, Iron and the Maiden. In addition to their inhouse game team, Naughty Dog is also home to the ICE Team, one of PlayStation Studios's central technology groups. The company's first PlayStation 3 game, Uncharted Drake's Fortune, was released in 2007, followed by several sequels and spin-off titles. Naughty Dog was previously known for having a history of developing one game at a time, and also one franchise per console, a controversial trend that was criticized by fans. This lasted until Naughty Dog announced a new intellectual property for the PlayStation 3, The Last of Us, which was in development by a secondary team at the studio and released to critical acclaim in 2013. A sequel, The Last of Us Part II for PlayStation 4, was released by Naughty Dog in 2020 to similar acclaim, though the narrative polarized critics and audiences.
