The Salza is a river of Saxony-Anhalt state, in Germany. It is a left tributary of the Saale in Salzmünde.
The upper section of the Salza carries the name Querne. Its source is near the village, a district of the town Querfurt. It flows through Querfurt to Obhausen, where it receives its right tributary Weidenbach. Downstream from this confluence, the river carries the name Weida. It continues through Schraplau and Röblingen am See and near Langenbogen it receives water that is pumped out of the lake (fed by the river Böse Sieben). From this point it carries the name Salza. The Salza proper is long; including Querne and Weida, it is long.
