Gu-Win is a town in Fayette and Marion counties. It incorporated in 1956. At the 2010 census the population was 176, down from 204. Despite occupying a small amount of land in Fayette County, all of the population resides in Marion County.
The town’s unusual name is taken from part of two neighboring cities, Guin and Winfield. “Gu-Win” and “Guin” are not the same, though the pronunciation is virtually the same, leading to occasional confusion by visitors.
The area Gu-Win occupies is between Guin and Winfield. Until the 1950s, it was initially known as Ear Gap. Not wanting to be annexed into Guin, it pursued incorporation for itself, and chose the name of the local drive-in theater, “Gu-Win.” As of 2016, the theatre still operates, but has been renamed the Blue Moon.
