Querbach is a river of Bavaria, Germany. It is the left headwater of the Westerbach.
The Querbach rises in the Arzborn (sometimes called Atzborn), a larger spring on the Hoher Querberg (474 m). It is located northeast of Westerngrund, in the Atzborn forest area, near the state border with Hesse. The spring water flows from a small opening on the mountainside.
The Querbach runs in a southwesterly direction to Huckelheim. There it unites with the Huckelheimer Bach to form the Westerbach.
