Reptilian is a bobsled roller coaster located at Kings Dominion in Doswell, Virginia, United States.

Manufactured by Mack Rides, the roller coaster debuted as Avalanche in 1988 and was renamed to Reptilian in 2022 following a refurbishment.

In late 1987, Kings Dominion announced that a bobsled roller coaster named Avalanche at the time would be added for the 1988 season.

During the 2021-2022 off-season, Avalanche was repainted orange and rethemed as Reptilian as part of the park's new Jungle X-Pedition area.
