The Biela (German name) or Bělá or Ostrovská Bělá (Czech names) is a river in eastern Germany and northern Czech Republic, a left tributary of the Elbe. The source is near Ostrov hamlet in the municipality of Tisá, in the Bohemian Switzerland, northwest of Děčín. After a few km it crosses into Saxony (and the Saxon Switzerland). The town Königstein is located at the confluence of the Biela with the Elbe.
