Six Flags America is an amusement park in Woodmore, Maryland, United States, near Upper Marlboro, adjacent to the Washington, DC metropolitan area.
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 features colonial-era architecture and related theming of Colonial Maryland. On May 1, 2025, Six Flags announced that the park would close following the conclusion of the 2025 operating season on November 2, 2025.
