Location of Ash Creek in Oregon

Ash Creek is a short stream in Polk County, in the U.S. state of Oregon. Formed by the merger of its north and middle forks near Monmouth, it flows generally east to meet the Willamette River at Independence. The creek passes under Oregon Route 51 just before entering the river. The creek's mouth is about 95 miles (153 km) upstream of the Willamette's confluence with the Columbia River.

North Fork Ash Creek begins at the eastern edge of the Central Oregon Coast Range near Dallas at 44°54′35″N 123°21′44″W / 44.90972°N 123.36222°W / 44.90972; -123.36222 (North Fork Ash Creek) and flows generally southeast to meet the Middle Fork. Middle Fork Ash Creek begins at 44°53′26″N 123°17′37″W / 44.89056°N 123.29361°W / 44.89056; -123.29361 (Middle Fork Ash Creek) near Mount Pisgah and flows generally east. Both forks pass under Oregon Route 99W shortly before they merge to form the main stem.
