Six Flags America is a decommissioned 131-acre (53 ha) amusement park in Woodmore, Maryland, United States. Owned by Six Flags, it is located near Upper Marlboro, Maryland, and in the Washington, DC, metropolitan area. It had a water park named Hurricane Harbor Maryland.
Founded as a wildlife center in 1974 by Ross Perot, ABC television operated the park as a drive-through safari called The Largo Wildlife Preserve, from 1974 until its closure in 1978. The property was bought by Jim Fowler's Wild Kingdom; thereafter, the site was gradually converted from a wildlife preserve into a theme park named Wild World. In 1992, the park was renamed Adventure World after being acquired by Premier Parks.
The park was rebranded as the tenth Six Flags park, after Premier Parks acquired Six Flags Inc., and adopted its name in 1999; the name-change to Six Flags America—and all associated IP and theming—was unveiled for the park's 1999 operating season. The "America" in the park's name was chosen due to the park's close proximity to the U.S. capital; the park's entry plaza and "promenade" also featured colonial-era architecture and related theming of Colonial Maryland.
Six Flags announced on May 1, 2025, that Six Flags America and Hurricane Harbor Maryland would close permanently at the end of the 2025 season. The water park permanently closed on September 6, and Six Flags America permanently closed on November 2, 2025.
