RMS Cedric was an ocean liner owned by the White Star Line. She was the second of a quartet of ships over 20,000 tons, dubbed The Big Four, and was the largest vessel in the world at the time of her entering service. Her career, peppered with collisions and minor incidents, took place mainly on the route from Liverpool to New York. During the 1920s, the Cedric had to face competition from increasingly modern ships. After having been refitted several times to adapt to new clienteles, she was withdrawn from service in 1931 and scrapped the following year.
