Nehalem is a city in Tillamook County, Oregon, United States. Incorporated in 1889, the city is located on the Nehalem River at Nehalem Bay of the Pacific Ocean. It is bisected by U.S. Route 101. The population was 203 at the 2000 census.
Nehalem was named for the Nehalem Indians. They were also known as the Tillamook.
Nehalem was once a thriving logging community, but with the decline of the logging industry, the local economy has drastically declined. The city used to stretch out over the river on log planks, where a lumber mill once cut the logs that came down a railroad track on the Nehalem River. Wood pilings that held up this railroad track can still be found in the North Fork Nehalem River. On the front face of Nehalem Elementary school there is an original facade which says "Union High School" from when the area was more populous and could support both an elementary school and a high school. Currently there is an elementary school and a community pool with a small annex which hosts a few classes for Tillamook Community College.
