The Pleiße is a river of Saxony and Thuringia, Germany. The Pleiße has its source southwest of Zwickau at Ebersbrunn, then flows through Werdau, Crimmitschau, Altenburg, and other towns and villages in Saxony and Thuringia, before flowing from the right into the White Elster in Leipzig. The river originally had a natural length of 115 km; however, south of Leipzig, it has been straightened, which shortened it to around 90 km.
