RMS Strathmore was an ocean liner and Royal Mail Ship of the Peninsular and Oriental Steam Navigation Company (P&O), the third of five sister ships built for P&O in the "Strath" class. Launched in 1935, she served on the company's route from London to India until 1940, when she was requisitioned for war service as a troop ship, and redesignated as SS Strathmore, until being returned to her owners in 1948. After a long re-fit, she resumed service with P&O from 1949 until 1963, when she was sold to Latsis Lines and renamed Marianna Latsi, then Henrietta Latsi, before being laid up in 1967 and finally scrapped in 1969.
