RMS (later HMT) Olympic was a transatlantic ocean liner, the lead ship of the White Star Line's trio of Olympic-class liners. Unlike her younger sister ships, Olympic enjoyed a long and illustrious career, spanning 24 years from 1911 to 1935.

This included service as a troopship during the First World War, which gained her the nickname 'Old Reliable'. Olympic returned to civilian service after the war and served successfully as an ocean liner throughout the 1920s and into the first half of the 1930s, although increased competition.
