Grand Theft Auto: Vice City is a sandbox-style action-adventure computer and video game designed by Rockstar North (formerly DMA Design) and published by Rockstar Games. It is the second 3D game in the Grand Theft Auto video game franchise and fourth original title overall. It debuted in North America on October 27, 2002, for the PlayStation 2 and quickly became the best-selling video game for that year. As of July 2006, Vice City was, in the American market, the best-selling PlayStation 2 game of all time. Vice City also appeared on Japanese magazine Famitsu's readers' list of all-time favorite 100 videogames in 2006. Following this success, Vice City saw releases in Europe, Australia and Japan, and became available on the PC. Rockstar Vienna also packaged the game with its predecessor, Grand Theft Auto III, and sold it as Grand Theft Auto: Double Pack for the Xbox. Vice City was succeeded by Grand Theft Auto: San Andreas and preceded by Grand Theft Auto III.

Vice City draws much of its inspiration from 1980s American culture. Set in 1986, the story revolves around Mafia member Tommy Vercetti, who was recently released from prison. After being involved in a drug deal gone wrong, Tommy is forced to seek out those responsible. Throughout the game, Tommy forges out a criminal empire in Vice City, gradually obtaining contacts, running businesses and seizing power from the other criminal organizations present in the city.

The game uses a tweaked version of the game engine used in Grand Theft Auto III and similarly presents a huge cityscape, fully populated with buildings (from hotels to skyscrapers), vehicles (cars, motorcycles, boats, helicopters) and people to explore.

Vice City's setting is also revisited in Grand Theft Auto: Vice City Stories, which serves as a prequel to events in Vice City.
