Rincon is a city in Effingham County, Georgia, United States. The population was 8,836 at the 2010 census, up from 4,376 in 2000. It is part of the Savannah Metropolitan Statistical Area.
Rincon, in the southeast area of Effingham County, Georgia, was incorporated as a city in 1927. While the earliest settlers came to the area in 1751, the area had little development until the late 19th century.
During the American Civil War, when forces of the Union Army penetrated the South, thousands of slaves escaped from plantations to go to their lines. Many fell in with the forces of Union General William Tecumseh Sherman and followed his March to the Sea. Hundreds of fugitive African-Americans drowned during the campaign while trying to cross Ebenezer Creek near the site of present-day Rincon, outside of Savannah. In 2010 the Georgia Historical Society erected a historical marker about this event, as part of a major project to memorialize little-known events from the Civil War era and recognize African-American sacrifices for freedom.
Rincon's development was catalyzed by the coming of the railroad in the 1890s. A rail line was built from the Carolinas across the state line at the Savannah River and southward to Savannah.
