Albina Engine & Machine Works was a shipyard along the Willamette River in Portland, Oregon, United States. It was located in the Albina area of Portland along N. River Street and N. Loring Street. Albina Engine & Machine Works was founded in 1904. The shipyard produced a number of freighters during World War I, but operated mainly as a repair yard during the 1920s and 1930s. The Albina yard expanded its workforce and production during Portland's World War II shipbuilding boom. It specialized in producing subchasers, vessels designed to combat German U-boats. Albina Engine & Machine Works also built Landing Craft Support boats and cargo ships. Business declined in the post-war years, and Albina Engine & Machine Works was sold to the Dillingham Corporation around 1971.

The Landing Craft, Support (Large) were two distinct classes of amphibious warfare vessels used by the United States Navy (USN) in the Pacific and the Royal Navy in World War II. The USN versions, which were later reclassified Landing Ship Support, Large, also performed radar picket duty and fire fighting.
