The Georgia World Congress Center (GWCC) is a convention center in Atlanta, Georgia, U.S. Enclosing some 3.9 million ft2 in exhibition space and hosting more than a million visitors each year, the GWCC is the world's largest LEED certified convention center and the fourth-largest convention center in the United States. Opened in 1976, the GWCC was the first state-owned convention center established in the United States. The center is operated on behalf of the state by the Georgia World Congress Center Authority, which was chartered in 1971 by Georgia General Assembly to develop an international trade and exhibition center in Atlanta. The authority later developed the Georgia Dome, Centennial Olympic Park, and Mercedes-Benz Stadium, which replaced the Georgia Dome. In 2017, the Georgia Dome was closed on March 5 and demolished by implosion on November 20 while Mercedes-Benz Stadium officially opened on August 26. While the GWCCA owns Mercedes-Benz Stadium, AMB Group, the parent organization for the National Football League's Atlanta Falcons and Major League Soccer's Atlanta United FC, is responsible for the stadium's operations.

A convention center is a large building that is designed to hold a convention, where individuals and groups gather to promote and share common interests. Convention centers typically offer sufficient floor area to accommodate several thousand attendees. Very large venues, suitable for major trade shows, are sometimes known as exhibition halls. Convention centers typically have at least one auditorium and may also contain concert halls, lecture halls, meeting rooms, and conference rooms. Some large resort area hotels include a convention center.
