a river of Germany, a left-bank tributary of the Elbe. It is formed by the confluence, just below Kolditz, of the Zwickauer Mulde, which rising in the Vogtland of Saxony passes Zwickau, Glauchau and Rochlitz, and the Freiberger Mulde, which, rising in the Bohemian Erzgebirge, touches Freiberg, Dobeln and Leisnig. The united river flows north to Grimma and thence past Wurzen, Eilenburg and Bitterfeld to Dessau, where it joins the Elbe. The total length of the united river is 75 m.
