The North Yamhill River is a 31-mile (50 km) tributary of the Yamhill River in the U.S. state of Oregon. It drains an area of the Northern Oregon Coast Range, as well as part of the Willamette Valley west of the Willamette River.[4][6]

Rising in a remote area in the mountains of northwestern Yamhill County, the river flows generally east, then southeast, then south past the city of Yamhill. It joins the South Yamhill River about 2 miles (3.2 km) east of McMinnville to form the Yamhill River.[4][6]
