Rockdale County is a county located in the U.S. state of Georgia. As of the 2010 census, the population was 85,215. The county seat is Conyers.

Rockdale County is included in the Atlanta-Sandy Springs-Roswell, GA Metropolitan Statistical Area.

Rockdale County was created on October 18, 1870 and received its name from Rockdale Baptist Church (est. 1846), which was named after the granite strata that rests under the county's red clay top soil. A bill introduced by John F. Hardin and John Harris carved Rockdale out of the northern portion of Newton County; parts of Rockdale County also came from neighboring Henry, Walton, Gwinnett, and DeKalb counties. Conyers, Rockdale's only incorporated town and urban center, became the county seat.

Prior to Rockdale becoming a county, the land had been inhabited by the Creek and Cherokee; the boundary between the two native nations, the Hightower Trail, ran directly through area. Burial remains have been discovered in the Honey Creek and Hi-Roc areas. Whites began migrating to the area in the early 19th century and initial white settlers suffered from Indian raids. Early white settlements developed along Big Haynes Creek in the northern part of the county, the Yellow River in the middle portion of the county, and Honey Creek in the south. Communities formed around grist mills and newly formed churches such as Haralson Mill, Costleys Mill, Dial Mill, Zacharys Mill, McElroys Mill, Union Grove Baptist Church, Ebenezer Methodist Church, Philadelphia Methodist Church, Salem Baptist Church, Smyrna Presbyterian Church, Pleasant Hill Baptist Church, Bethel Christian Church, Honey Creek Baptist Church. Other communities included Magnet and Zingara. These settlers were largely subsistence farmers.
