The Pacific Coast Steamship Company was an important early shipping company that operated steamships on the west coast of North America. Organized in 1867 under the name of Goodall, Nelson and Perkins, the company effectively ceased business in 1916 when its vessels were purchased by the Admiral Line. The Admiral Line (also American Mail Line, and later Admiral Oriental Line) was a steamship company based in Seattle which operated five ocean liners sailing from Seattle to Japan and China. The Admiral Line also adopted the name "The Pacific Steamship Company", which it used until 1936 when operations ceased.

This image of the Admiral Line terminal was taken facing northeast at Seattle's waterfront on Pier D at 1519 Railroad Avenue South. The steam stack of an Admiral Line ship can be seen on the opposite side of the terminal, and the Smith Tower on Second Avenue is visible in the distance.
