Montgomery is an unincorporated community and census-designated place (CDP) in Chatham County, Georgia, United States.

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 failed to maintain a permanent settlement, due to poor location and disease, and therefore lost their grant.

The northeast border of the CDP is formed by Georgia SR 204 Spur, which leads to Skidaway Island.

[17] As of the 2020 United States census, there were 4,443 people, 1,609 households, and 1,161 families residing in the CDP.
