The Middle Fork Willamette River is one of several forks that unite to form the Willamette River in the western part of the U.S. state of Oregon. It is approximately 115 miles (185 km) long, draining an area of the Cascade Range southeast of Eugene, which is at the southern end of the Willamette Valley.
