The Molalla River is a 51-mile (82 km) tributary of the Willamette River in the northwestern part of Oregon in the United States. Flowing northwest from the Cascade Range through Table Rock Wilderness, it passes the city of Molalla before entering the larger river near Canby. The Molalla is the largest Willamette tributary unblocked by a dam.
