Thunder River is a river rapids ride located at two American amusement parks. The first opened in 1980 at Six Flags AstroWorld in Houston, Texas, which was the first of its kind in the world. The popularity led to other similar installations at various Six Flags theme parks throughout the 1980s. Only two with this name remain. One currently operates at Six Flags Over Georgia in Austell, Georgia; the other operates at Six Flags St. Louis in Eureka, Missouri.
