Rincon sits inland in southeastern Effingham County, northwest of Savannah, on the mainland well back from the Savannah River. It grew up around the railroad at the end of the nineteenth century and incorporated on August 3, 1927, and GA Highway 21 runs north through it from I-95 Exit 109.
The city has grown steadily. The Census counted 10,934 residents and 4,347 housing units in 2020, and the estimate for July 2025 was 11,726, seven percent above the count. Rincon is far enough from the port and the airport that their expansion reaches it gently rather than all at once.
The work is in town. Georgia-Pacific’s environmental filing puts its Savannah River mill at 437 Old Augusta Road South, making tissue, towels and napkins, and Effingham County describes Rincon as its retail center for the surrounding area.
The city keeps its own parks and the start of a long drive. The Macomber Park Complex is at 1004 Lexington Avenue, with Peter J. Giles Park and Patriot’s Park also run by the Recreation Department, and the Historic Effingham-Ebenezer Scenic Byway, a sixty-mile state-designated route through Rincon, Ebenezer, Guyton and Springfield, begins here at Fourth Street. Effingham County Schools serves the city and runs Rincon Elementary.
One landmark along that byway belongs to the county rather than the city. The Ebenezer Townsite and Jerusalem Lutheran Church, listed on the National Register in 1974, stand in unincorporated Effingham County on the Savannah River bluff.
