San Diego is the first city in Midnight Club 3: DUB Edition.
The player begins the Career mode game here, in Oscar's Six-One-Nine Garage. After defeating the racers here, the game proceeds to Atlanta where a DUB Tournament is taking place.
The city has the smallest map of all the three cities in Midnight Club 3: DUB Edition (four including Tokyo in Midnight Club 3: DUB Edition Remix). There is a freeway that travels through majority of the city.
The city also features a harbor, a fairground (possibly Belmont Park) by the beach, houses, industrial area, beach, the San Diego Zoo, Balboa Park, Petco Park (which can be driven through as a shortcut in races), a Water Park (based on real-life Sea World), and more where many races take place. The game's rendition of the city also features the San Diego Naval Base with the USS Kitty Hawk (which can be driven on as a shortcut during races) and a drydocked submarine, as well as Marine Corps Recruit Depot San Diego (labelled in-game as "MILITARY AREA").
San Diego also features a trolley system that features moving trolleys, which serve as one of the most dangerous obstacles in the game; colliding with one will cause the player to come to an instant stop and be pushed out of the way by the train. This also happens with the subway trains in Detroit.
There is a mall here that can be driven through and used as a shortcut, as well as other buildings with glass entrances and parking lots that can also be driven through and used as a shortcut. This city is the only city where it is possible to fall into the ocean (excluding Tokyo). Doing so will cause the player to slowly be sent back onto the road, wasting time. Police in this city use the Chevrolet Impala (SD Cop) and the Kawasaki Police 1000, and will give chase to speeding racers. Being the first cop car in the game, the Chevrolet Impala (SD Cop) is the slowest cop car in the game, while the Police 1000 is one of the fastest cop vehicles and motorcycles in the game.
