The Pacific-Alaska Navigation Company was an American passenger and freight ocean shipping company that operated between 1912 and 1916 on the West Coast of North America. It was formed as a holding company during the merger of the Alaska Pacific Steamship Company and the Alaska Coast Company. During its four years of life, its fleet became known as the Admiral Line because its ships (for example, the Admiral Watson) were usually named for former U.S. Navy admirals. The company was operated by president H.F. "Bert" Alexander, a former Tacoma longshoreman who worked his way up the ranks.
