Location of the mouth of the Nehalem River in Oregon

The Nehalem River is a river on the Pacific coast of northwest Oregon in the United States, approximately 119 miles (192 km) long. It drains part of the Northern Oregon Coast Range northwest of Portland, originating on the east side of the mountains and flowing in a loop around the north end of the range near the mouth Columbia River. Its watershed of 855 square miles (2,210 km2) includes an important timber-producing region of Oregon that was the site of the Tillamook Burn. In its upper reaches it flows through long narrow valley of small mountain communities but is unpopulated along most of its lower reaches inland from the coast.

The Nehalem River passing through Mist in winter and summer

It rises in the northeast corner of Tillamook County, in the Tillamook State Forest. It initially flows northeast, across the northwest corner of Washington County and into western Columbia County, past Vernonia and Pittsburg. At Pittsburg, it looks to the northwest and west into Clatsop County, then flows southwest back into northern Tillamook County. It enters Nehalem Bay on the Pacific in an estuary at Nehalem, about 70 miles (110 km) west-northwest of Portland. Near its mouth on the Pacific, the river passes under U.S. Route 101.

It receives the Salmonberry River from the east in northern Tillamook County. It receives the North Fork Nehalem River 25 miles (40 km) from the north about 2 miles (3.2 km) northwest of Nehalem, just before entering Nehalem Bay.
