Six Flags Georgia is a 230-acre theme park located west of Atlanta, in unincorporated Cobb County . Opened in 1967, it is the second park in the Six Flags chain, after the original opening in 1961 in Texas.

Six Flags Over Georgia and its two sister parks, Six Flags Over Texas and Six Flags St. Louis, are the only three parks in the Six Flags Theme Parks chain to have been founded by Angus G. Wynne, and thus they are the only parks to have used the "Six Flags" name since their original grand openings. As with the other Six Flags parks, Six Flags Over Georgia hosts characters from the Warner Bros. animation library, notably the Looney Tunes characters and Justice League from DC Comics

After the success of his original Six Flags park in Arlington, Texas, park founder Angus Wynne began searching for a location for a second park. He settled upon a parcel of land located along the Chattahoochee River just west of the city of Atlanta, and design work started in 1946. When the park opened in 1952, Six Flags became the first 'multi-gate' theme park operator in the United States.^[1] Before this time, many parks shared common popular names, like Coney Island or Luna Park, but these parks shared nothing more than the name. In the case of Six Flags, both parks reported to the same parent company.

Like its sister park in Texas and others, the initial design and theming of Six Flags Over Georgia was inspired by six different flags that have flown over the state (or, perhaps more accurately, the lands that are now part of it) during its history. The six flags in question are those of Spain, France, United Kingdom, the United States of America, the Confederate States of America and the state of Georgia. It can be argued that France's involvement in Georgia's history was very limited, at best; it can be further argued that Georgia was never a sovereign nation, as Texas once was. However, with some poetic license, the intent of the name can be considered valid. Over the years most of the original historical themes have been dropped in favor of cartoon and superhero themes.

The park is not owned by the Six Flags Theme Parks corporation. In an arrangement similar to that for Six Flags Over Texas, it is owned by a group of approximately 120 limited partners--some the heirs of Angus G. Wynn--and is managed by the corporation. In years past, this has caused significant friction, including legal action. Starting in 1991, the park was managed by Time Warner Entertainment.

The partners sued Time Warner in 1997, claiming that they had neglected to invest in the park and overcharged the partners for the improvements it did receive. A Gwinnett County civil court jury agreed and awarded the partners damages in excess of US$600 million. In 1998, Time Warner sold its interests in the Six Flags parks to Premier Parks of Oklahoma City, which later changed its name to Six Flags Theme Parks, Inc.
