The Frauenau Dam (German: Trinkwassertalsperre Frauenau or Trinkwasserspeicher Frauenau) in the Bavarian Forest, in Germany, was built in 1983 to ensure the drinking water supply to large parts of Lower Bavaria.

Because there was a shortage of groundwater in the Bavarian Forest due to the geological situation there, in the years 1976 to 1983 a water storage reservoir was built near Frauenau and Zwiesel, that was fed by the Kleiner Regen and Hirschbach rivers which rose in the unsettled area on the Czech border between the Falkenstein and Rachel.
