The community got its unusual name, according to locals, when, in the 1840s, a Classics teacher combined the Greek words "Litho" meaning "rock" and "Onia" meaning "place." Considering that the East Dekalb area contains an abundance of Gneiss granite, the teacher aptly chose the name Lithonia.

The nearby granite dome, Stone Mountain, is composed largely of a rock called Lithonia gneiss.
