The Los Angeles Steamship Company or LASSCO was a passenger and freight shipping company based in Los Angeles, California. The company, formed in 1920, initially provided fast passenger service between Los Angeles and San Francisco. In 1921, LASSCO added service to Hawaii in competition with the San Francisco-based Matson Navigation Company using two former North German Lloyd ocean liners that had been in U.S. Navy service during World War I. Despite the sinking of one of the former German liners on her maiden voyage for the company, business in the booming 1920s thrived, and the company continued to add ships and services. The worsening economic conditions in the United States, and the burning of another ship in Hawaii, caused financial problems for the company. After beginning talks in 1930, the Los Angeles Steamship Company was taken over by Matson Navigation on January 1, 1931, but continued to operate as a subsidiary until it ceased operations in 1937.
