Rita, formerly known as Rita: Queen of Speed, is a launched roller coaster located in the Dark Forest section of Alton Towers amusement park in Staffordshire Moorlands, England. Designed by Intamin, the Accelerator Coaster model opened to the public on 1 April 2005. It features an acceleration from 0 to 98.3 km/h (61.1 mph) in 2.5 seconds. The ride is loosely-themed to a drag racing concept, which partly changed when the section of the park transformed from "Ug Land" into the "Dark Forest" in 2010, when the ride TH13TEEN was added into that section. It is now themed as an abandoned drag racer that is used as the escape cart to escape the Dark Forest.

The launched roller coaster is a modern form of roller coaster. A launched coaster initiates a ride with high amounts of acceleration via one or a series of linear induction motors (LIM), linear synchronous motors (LSM), catapults, tires, chains, or other mechanisms employing hydraulic or pneumatic power, along a launch track. This mode of acceleration powers many of the fastest roller coasters in the world.
