Schwarzbach (; is a river in Bavaria, Germany, and a left tributary of the Günz.

It is 11.24 km long and joins the Günz northwest of Wattenweiler, in the municipality of Neuburg an der Kammel, at an elevation of about 482m above sea level, having descended roughly 68m from its source. The Günz is itself a left tributary of the Danube, so the Schwarzbach's waters ultimately drain into the Black Sea. The river lies within the Landkreis Günzburg, in the administrative region of Swabia.
