The Port of Columbia County is a special district in Columbia County, Oregon. The boundaries of the port district span 51 miles along the Columbia River from the Clatsop County line in the northwest of Columbia County, to the Multnomah County line in the southeast, and includes the cities of Scappoose, St. Helens, Columbia City, Prescott, Rainier, and Clatskanie.

The Port was created in 1940 under Oregon Revised Statute (ORS) Chapter 777 to promote economic development opportunities in the district, primarily through the lease and development of industrial properties. Originally called the Port of St. Helens, the Port was renamed in 2018 to be more representative of the entire district.

Today, the Port of Columbia County owns 10 different property sites and 2,400 acres of land, including industrial properties with excellent highway, rail and river access, and a deep-water dock at Port Westward for maritime access to the Pacific Ocean.

The Port also owns and manages recreational properties at the Scappoose Airport,  Bayport RV Park, and Scappoose Bay Marine Park.
