The Pacific Steam Navigation Company (Spanish: Compañía de Vapores del Pacífico) was a British commercial shipping company that operated along the Pacific coast of South America, and was the first to use steam ships for commercial traffic in the Pacific Ocean.[1] At one point in the 1870s, it had the world's largest merchant steamship fleet. The company continued in business until 1965, when it was purchased by another company, but it survived in name through a succession of ownership changes until at least the 1980s.[2]
