DeKalb County (/dəˈkæb/, /ˌdˈkæb/ də-KAB, DEE-KAB) is located in the north central portion of the U.S. state of Georgia. As of the 2020 census, the population was 764,382,[1] making it Georgia's fourth-most populous county. Its county seat is Decatur.[2]

DeKalb County is included in the Atlanta–Sandy Springs–Roswell metropolitan area. It contains roughly 10% of the city of Atlanta (the other 90% lies in Fulton County).[3] Stonecrest is the largest city that is entirely within the county. DeKalb is primarily a suburban county.

In recent years, some communities in North DeKalb have incorporated, following a trend in other suburban areas around Metro Atlanta. Stonecrest, Dunwoody and Brookhaven are now the largest cities that are entirely contained within the county.
