Roar (trademarked as ROAR) is the name of a wooden roller coaster at Six Flags America located near Upper Marlboro, Maryland. There were originally two roller coasters; the first and current ride was built in 1998 at Six Flags America, and a second ride was built in 1999 at Six Flags Discovery Kingdom. Both rides were designed and built by Great Coasters International (GCI).
