The Kreisliga Südmain (English: District league South Main) was the highest association football league in parts of the German state of Hesse from 1919 to 1923. The league was disbanded with the introduction of the Bezirksliga Main in 1923. The league is named after the river Main, which flows through Frankfurt am Main and reaches the Rhine near Mainz. The league was formed from clubs from the southern side of the river, around the Offenbach am Main area. With two clubs from Aschaffenburg, it also included teams from the Bavaria.
