Columbia River Shipbuilding Company

West Corum, one of the "West" boats built by the Columbia River Shipbuilding Company

The Columbia River Shipbuilding Company was a small shipyard in Portland, Oregon, United States, located on the west bank of the Willamette River. The shipyard was located at the foot of SW Sheridan Street, just upstream of the Interstate 5 Marquam Bridge.

The owners of Columbia River Shipbuilding were A. F. Smith and J. Frank Watson, who were also owners of the Smith and Watson Iron Works. The shipyard was managed by Charles D. Bowles, who was also associated with J. F. Duthie Shipbuilding of Seattle, Washington. Columbia River Shipbuilding was established in 1918 to build cargo ships for the Template:USSB. The shipyard closed shortly after the end of World War I.

Most of the 32 ships built by the Columbia River Shipbuilding Company were the West boats, a series of 5,600 GRT steel-hulled cargo ships built for the Template:USSB on the West Coast of the United States as part of the World War I war effort. The first ship built at Columbia River Shipbuilding was the cargo ship Westward Ho; the final ship completed was the cargo ship West Hassayampa, completed in January 1920.
