The Gottleuba is a small river in the Czech Republic and in Saxony, Germany. It is a left tributary of the Elbe. The Gottleuba's source is in the eastern part of the Ore Mountains in Krásný Les within the municipality of Petrovice. After a few km, it crosses the Czech-German border and flows the rest of its 34 km in Saxony. It passes the Gottleuba Dam and the town Bad Gottleuba-Berggießhübel, and flows into the Elbe in Pirna. In July 1927, there was a flash flood in the river due to heavy rain.
