The White Elster (German: Weiße Elster [ˌvaɪsə ˈʔɛlstɐ] ; Czech: Bílý Halštrov) is a 257-kilometre-long (160 mi) river in central Europe. It is a right tributary of the Saale. The source of the White Elster is in the westernmost part of the Czech Republic, in the territory of Hazlov. After a few kilometres, it flows into eastern Germany where it cuts through the Vogtland in (according to the Encyclopædia Britannica) a "deep and picturesque valley". In Germany it flows through the states of Saxony, Thuringia and Saxony-Anhalt. The White Elster flows through the cities of Plauen, Greiz, Gera, Zeitz, Pegau and Leipzig, and into the river Saale in Halle.
