SS Roosevelt was an American steamship of the early 20th century. She was designed and constructed specifically for Robert Peary′s polar exploration expeditions, and she supported the 1908 expedition in which he claimed to have discovered the North Pole. After her career with Peary, Roosevelt saw commercial use as a tug. She also operated as a United States Bureau of Fisheries supply ship and served as a United States Navy patrol vessel during World War I.
