Giant Drop is a drop tower ride located at Six Flags Great America in Gurnee, Illinois, United States. Manufactured by Intamin, the ride opened to the public on April 26, 1997, as part of a three-phase plan for the park's Southwest Territory area. The attraction opened alongside Dare Devil Dive, a skycoaster attraction, in the County Fair section of the park.
Set in the Loco Diablo Mine, the ride is themed as an ore excavator built by the fictional Southwest Mining Company. The ride received a temporary re-theme in 2017 under the name Drop of Doom featuring virtual reality headsets in partnership with Samsung. At a height of 227 ft (69 m), the ride is the second tallest attraction at Six Flags Great America, behind Sky Trek Tower at 330 ft (100 m).
