RMS Otranto was an ocean liner that was built for the Orient Steam Navigation Company in 1925. The "RMS" prefix stands for Royal Mail Ship, as she carried overseas mail under a contract between Orient Line and Royal Mail. Otranto was in service until 1957, when she was sold for scrap. The ship was named after the town of Otranto in Apulia in southern Italy. She was Orient Line's second ship of that name. The first was a 1909 passenger liner that in 1914 became the armed merchant cruiser HMS Otranto and in 1918 was lost as a result of a collision.
