Paramount's AstroWorld is a seasonally operated theme park located in Houston, Texas. Owned and operated by Paramount Parks, a division of Paramount Motion Pictures Group, itself owned by Viacom, the park is located on approximately 57 acres (23 ha) of land, which was later expanded to over 75 acres (30 ha) between Kirby Drive and Fannin Avenue, directly south of Loop 610 in Houston. Part of the "Paramount Houston" complex, the park also includes Paramount's WaterWorld, a water park that is adjacent to the main park.

The park opened on June 1, 1968, and was originally developed and constructed as part of the Astrodomain, the brainchild of local philanthropist and former Houston mayor Judge Roy Hofheinz, who intended it to complement The Astrodome.[1]

AstroWorld was sold to the Six Flags Corporation by the Hofheinz family in 1975. Although it was the fourth theme park to be included in the Six Flags family, it was the first to be acquired by that company rather than built from the ground up. Initially, it was marketed as "AstroWorld: A Member of the Six Flags Family" so as to not confuse patrons with Six Flags Over Texas in Arlington.

Six Flags sold off AstroWorld to Viacom in October 2005. Viacom then placed AstroWorld under its Paramount Parks division.
