Hydra the Revenge is a steel floorless roller coaster at Dorney Park & Wildwater Kingdom in South Whitehall Township, Pennsylvania. It was built where the Wooden roller coaster Hercules stood, which was closed for demolition at the end of the park's 2003 season.

Hydra is the first roller coaster in the United States with an inversion before the lift hill. This inversion is an inline twist, and is popularly known as the "Jojo roll".
