Crazy Taxi is a series of score attack racing video games that was developed by Hitmaker and published by Sega. The first game appeared in arcades in 1999 and was very successful, prompting Sega to port the arcade version to their Dreamcast console in 2000.

Crazy Taxi and its sequels are score attack games that all employ the same fundamental rules and mechanics. The player controls one of several taxi drivers in a fictional city, looking for fares and then taking them to their destination in the fastest time possible. The player must perform this while time still remains on an overall gameplay clock. Passengers looking for rides are indicated by an overhead marker that is colored to represent the distance to their intended destination. The color marker ranges from red indicating short trips, to yellow for intermediate distances, and to green indicating long ones. When a passenger is picked up, the player is awarded additional time on the countdown time. Furthermore, a second countdown timer is started, representing how quickly the passenger needs to be at their destination. While a passenger is in the taxi, a large green arrow is shown on the player's HUD that points in the general direction of the passenger's destination to help guide the player through the map.
