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.

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.
