Revenge of the Mummy, officially named Revenge of the Mummy: The Ride, is an enclosed roller coaster located at Universal Studios Florida, Universal Studios Hollywood, and Universal Studios Singapore. It is themed to The Mummy film franchise, and the ride features linear induction motors (LIMs) that launch riders to a maximum speed of 40 mph (64 km/h) in a matter of seconds. The Florida and Singapore locations have the same track layout, although each location offers a slightly different virtual experience. Manufactured by Premier Rides, the attractions feature track switches installed by Dynamic Structures. Universal Creative and ITEC Entertainment Corporation created the theme at each location, with Adirondack Studios responsible for several of the unique elements implemented at the Singapore location.

An indoor roller coaster or enclosed roller coaster is a roller coaster built inside a structure. The structure may be unrelated to the ride, or it may be intended solely or primarily for the ride. Many indoor coasters are custom made and placed in amusement parks or shopping malls. LaMarcus Adna Thompson, who pioneered the construction of the first simple roller coasters, initially built "scenic railway" rides including "indoor tableaux, panoramas, and biblical scenes illumined by car-tripped switches and flood lamps". A "completely enclosed roller coaster" called the Twister was built as early as 1925. Walt Disney World's Space Mountain was one of the first rides considered to be an indoor roller coaster, and was "the first indoor roller coaster where riders were in total darkness for the length of the ride so they couldn't tell where the drops or turns would occur".
