From the building of the Georgia Railroad, which travels through the city until at least the 1860s, the community was known as "Belair". The city was chartered by the Georgia Legislature and officially incorporated on January 1, 1881. The name of the small village purportedly came from the old Grove Baptist Church that was founded in 1808. A poet famous in the post-Civil War era, Paul Hamilton Hayne, moved to Copse Hill in the Parham Road area in the 1860s. He solicited the United States Postal Service to establish the Grovetown post office. The first U.S. mail service was inaugurated on September 28, 1877, with Charles Clifford as postmaster. Mr. Clifford was also the train depot agent and the owner of the corner store.
