Irwinville is an unincorporated community in Irwin County, Georgia, United States.
Irwinville was founded as "Irwinsville" in 1831 as the seat for the newly formed Irwin County. The community was named for Georgia governor Jared Irwin. It was renamed to Irwinville (without the S) when it was incorporated as a town in 1857. In 1907, the seat of Irwin County was transferred from Irwinville to Ocilla.
Irwinville is well known for its role in the American Civil War as the site of the capture of Confederate President Jefferson Davis, who was fleeing Union troops. Today, the site of his capture is marked by a monument as well as a museum and park.
It was also a part of the WPA projects in the 1930s. A small water park originally called Crystal Lake (later changed to Crystal Beach) operated just outside there from the middle of the twentieth century to 1998.
