Montgomery is an unincorporated community and census-designated place (CDP) in Chatham County, Georgia, United States. The population was 4,443 at the 2020 United States census, down slightly from 4,523 in 2010. It is a suburb of Savannah and is part of the Savannah metropolitan area.

Montgomery is believed to be the location of an early settlement in the Savannah area (prior to General Oglethorpe's land grant in 1733) founded by three brothers who were British baronets: William, James, and Robert Montgomery. They received a land grant in 1677. They failed to maintain a permanent settlement, due to poor location and disease, and therefore lost their grant. The brothers moved to the more established Virginia Colony. The name of the settlement continues in this area of Chatham county, as well as Old Montgomery Road, Montgomery Street, and Montgomery Cross Road.
