The White Main ( or Weißmain, not to be confused with the Weismain), is the larger and shorter of the two headstreams of the River Main. It rises in the Fichtelgebirge and merges near Steinenhausen, southwest of Kulmbach, with the left-hand, southern headstream, the Red Main, to form the Main. The length of the White Main is variously given as 41 km and 52.8 km. The source of the White Main lies on light granite rock, which lends it its white colouration.
