Thomas Crean (Irish: Tomás Ó Cuirín; c. 16 February 1877 – 27 July 1938) was an Irish seaman and Antarctic explorer who was awarded the Albert Medal for Lifesaving (AM). Crean was a member of three major expeditions to Antarctica during the Heroic Age of Antarctic Exploration, including Robert Falcon Scott's 1911–1913 Terra Nova Expedition. This saw the race to reach the South Pole lost to Roald Amundsen and ended in the deaths of Scott and his party. During the expedition, Crean's 35-statute-mile (56 km) solo walk across the Ross Ice Shelf to save the life of Edward Evans led to him receiving the Albert Medal.
