Clatsop County is a county in the northwest corner of the U.S. Pacific Coast. It lies along the mouth of the Columbia River and the Pacific Ocean and is home to coastal communities, forests and significant historical sites. The county seat is Astoria, and the population recorded at the 2010 census was 37,039. For official matters the county operates under the government functions typical of a county within the state of Oregon.

Geography and communities

Clatsop County's landscape combines ocean beaches, river estuaries and inland forests. The area includes small cities and towns, state parks, and parts of federally managed lands. Major population centers and communities include Astoria, Seaside, Cannon Beach and smaller coastal and river settlements. The county's position at the Columbia River mouth has shaped its climate, ecology and human activity.

History and name

The county takes its name from the Clatsop people, the Indigenous inhabitants of the coastal region. European‑American presence increased in the early 19th century with fur trading, and later maritime and fishing industries. The Lewis and Clark Expedition wintered at nearby Fort Clatsop, now preserved as part of the area's historic sites and museums.

Economy, culture and importance

The local economy blends tourism, commercial fishing, maritime services and forest products. Astoria serves as a cultural and economic hub with museums, historic districts and port activity. The scenic coastline, lighthouses and historical attractions draw visitors year‑round, and several local festivals and museums interpret the county's maritime and Indigenous heritage.
