Hephzibah () is a city in southern Richmond County, in the U.S. state of Georgia. It is part of the Augusta metropolitan area. The population was 4,011 at the 2010 census. Hephzibah is a poetic name used in the Book of Isaiah (62:4) to refer to Jerusalem, meaning "My delight is in Her."
Hephzibah was originally named Brothersville, in honor of three brothers who settled near one another. In October 1860, a Baptist seminary was established in Brothersville by a group of Appling residents. They established the Hephzibah Baptist Church in 1862. The prominence of these new religious institutions in the area swayed the state of Georgia to rename the town Hephzibah in 1870. In 1909, Walter A. Clark published a book of local history, named A Lost Arcadia - The Story of My Old Community, detailing the earliest days of Hephzibah.
In 1996 the governments of the city of Augusta and Richmond County combined to form a consolidated government. The residents of Hephzibah and nearby Blythe voted to maintain their separate city governments prior to this action. Some municipal services in Hephzibah are provided by the consolidated Augusta-Richmond County, while water, fire, and police services are maintained by the city.
