Rodach (German pronunciation: [ˈʁoːdax]) is a river in Bavaria, Germany. It is a right-bank tributary of the Main River, which it joins near the town of Hochstadt am Main. The river has a length of approximately 53.0 km (32.9 mi) and drains a basin area of about 1,010 km² (390 sq mi).
The Rodach flows through the western Franconian Forest (Frankenwald) region in northern Bavaria. Its largest tributaries are the Wilde Rodach (left tributary), the Haßlach (right tributary), and the Steinach (right tributary). Upstream of the confluence with the Wilde Rodach, the river is also known as the Zahme Rodach ("Tame Rodach") to distinguish it from its wilder counterpart.
The river's mouth is located at coordinates 50°09′26″N 11°09′12″E. The Rodach is part of the Main river system, which ultimately drains into the Rhine and then the North Sea.
