The park opened on May 16, 1975, adjacent to Anheuser-Busch's brewery and near its other developments including the Kingsmill Resort complex. The park is themed around various European countries.

The park was originally called Busch Gardens: The Old Country, reflecting the European theme. In 1993, the park was renamed Busch Gardens Williamsburg before briefly being named Busch Gardens Europe in 2006 until it returned to the Williamsburg name in 2008. Similarly, its sister park in Florida was originally called Busch Gardens: The Dark Continent until it was officially renamed Busch Gardens Tampa Bay until a brief switch to Busch Gardens Africa from 2006 to 2008. In 2015, the estimated attendance of 2.78 million makes it the twentieth most-visited park in the US.

In addition to its landscaping and European theme, Busch Gardens is widely known for its roller coasters, including Griffon, Alpengeist, and Apollo's Chariot, which won No. 4 best steel coaster in 2012 from the Golden Ticket Awards.
