The Inman Line was one of the three largest 19th-century British passenger shipping companies on the North Atlantic, along with the White Star Line and Cunard Line. Founded in 1850, it was absorbed in 1893 into American Line. The firm's formal name for much of its history was the Liverpool, Philadelphia and New York Steamship Company, but it was also variously known as the Liverpool and Philadelphia Steamship Company, as Inman Steamship Company, Limited, and, in the last few years before absorption, as the Inman and International Steamship Company.

The White Star Line was a British shipping line. Founded out of the remains of a defunct packet company, it gradually rose up to become one of the most prominent shipping companies in the world, providing passenger and cargo services between the British Empire and the United States. While many other shipping lines focused primarily on speed, White Star branded their services by focusing more on providing comfortable passages for both upper class travellers and immigrants.
