Resident Evil 3: Nemesis is a survival horror video game developed by Capcom and originally released for the PlayStation video game console in 1999. It is the third installment in the Resident Evil video game series and takes place before and after the events of Resident Evil 2. The story of the game follows Resident Evil protagonist Jill Valentine and her efforts to escape from a city that has been infected with a new type of biological weapon secretly developed by the pharmaceutical company Umbrella. The game uses the same engine as its predecessors and features 3D models over pre-rendered backgrounds with fixed camera angles.

Unlike previous Resident Evil games, Resident Evil 3: Nemesis was designed to have more action-oriented gameplay. It features a larger number of enemies for the player to defeat and introduces the eponymous Nemesis creature, which periodically pursues the player from one area to the next until the end of the game. The game was a critical and commercial success, selling more than three million units worldwide. Most critics praised the graphics for being detailed and the Nemesis creature as an intimidating villain, but some criticized the game's short length and story. After its release on the PlayStation console, Resident Evil 3: Nemesis was subsequently ported to the Dreamcast, Microsoft Windows and GameCube systems.
