A stand-up roller coaster is a roller coaster designed so that the rider stands throughout the course of the ride. Typically, the rider is restrained by an adjustable, bicycle-like seat and an over the shoulder restraint.

The first stand-up rollercoaster was King Cobra at Paramount's Kings Island which opened in 1984 and was designed and manufactured by Togo a Japanese rollercoaster manufacturer. King Cobra was dismantled in 2001.

The largest stand-up rollercoaster is Riddler's Revenge designed by Bolliger & Mabillard and located at Six Flags Magic Mountain in Valencia, California. It is 156 feet (47.5 meters) tall and has a 146 foot (44.5 meters) first drop. The track is 4370 feet (1332 meters) long and includes 6 inversions, the most of any stand-up rollercoaster. Riddler's Revenge opened on April 4, 1998.

While the stand-up rollercoaster has been popular with guests of amusement parks for its unusual riding position, a common complaint is of leg-discomfort. The design has had its phases of popularity, but recently it has not been in favor. The last stand-up rollercoaster constructed was the Georgia Scorcher at Six Flags Over Georgia built in 1999. Approximately 20 were built in the 15 years between 1984 and 1999.
