Lithonia (/lɪˈθoʊniə/ lih-THOH-nee-ə, AAVE: /laɪ-/ ly-) is a city in eastern DeKalb County, Georgia, United States. The city's population was 2,662 at the 2020 census. Lithonia is in the Atlanta metropolitan area.

"Lithonia" means "city/town of stone". Lithonia is in the heart of the Georgian granite-quarrying and viewing region, hence the name of the town, from the Greek lithos, for “stone”.^[4] The huge nearby Stone Mountain is composed of granite, while the Lithonia gneiss is a form of metamorphic rock. The Stone Mountain granite is younger than, and has intruded the Lithonia gneiss. The area has a history of rock quarries. The mines were served by the Georgia Railroad and Atlanta, Stone Mountain & Lithonia Railway. Some of the rock quarries have been converted to parkland, and the rail lines to rail-trail.

Lithonia is one of the gateways to the Arabia Mountain National Heritage Area,^[5] which is largely contained inside Stonecrest, Georgia.
