Underground Atlanta is a shopping and entertainment complex in downtown Atlanta, Georgia. First opened in 1969, it takes advantage of the viaducts built over the city's many railroad tracks to accommodate automobile traffic. Each level has two main halls, still called Upper and Lower Alabama and Pryor Streets.

Undergound is home to several clubs and bars in Kenny's Alley, and enjoys special exemptions including an open container provision allowing patrons to take alcoholic drinks from bar to bar, and a 4:00AM closing time that is 90 minutes later than the rest of the city. The complex has had difficult history and reputation among residents of Atlanta.
