South Fulton is a city within Obion County in extreme northwestern Tennessee, situated on the Tennessee and Kentucky State Line. South Fulton has a population of approximately 2,500 according to the 2010 census. It is approximately 40 miles east of Reelfoot Lake State Park and 130 miles north of Memphis, TN.

The South Fulton Municipal Complex includes the City Hall, Police Department, Fire Department, Public Works, the Twin Cities Railroad Museum, and the Twin Cities Chamber of Commerce office. The schools, South Fulton Elementary and South Fulton Middle/High School, are part of the Obion County school system.

Each year, South Fulton hosts a community Easter Egg Hunt and Bar-B-Que Competition on the grounds of the Municipal Complex. The city of South Fulton is considered a twin city with Fulton, Kentucky, and thus co-sponsors the annual Twin Cities Banana Festival. The Banana Festival commemorates the history of the Twin Cities’ railroad that provided an icing station for numerous bananas being transported north from New Orleans. A long-standing Banana Festival tradition includes the one-ton banana pudding that is marched through the parade and served to everyone at the end of the route.

In April 2016, the newly constructed Unity Park Amphitheater in South Fulton was the home for the first annual KYTN Country Music Festival with headliner Kellie Pickler and over 7,000 people in attendance. The second annual KYTN Country Music Festival on April 29, 2017, was a success with 5,000 people gathered at Unity Park to see several artists, including headliner Brett Young.
