The Eternal Sea (aka The Admiral Hoskins Story) is a 1955 American biographical war film directed by John H. Auer and starring Sterling Hayden, Alexis Smith and Ben Cooper. The film follows the career of Captain John Hoskins, who loses his leg at the Battle of Leyte Gulf and resists attempts to retire him and continues his military service after learning to cope with his disability. He goes on to be promoted to admiral and commands an aircraft carrier during the Korean War.

The Eternal Sea was one of a number of more ambitious productions by Republic Pictures, which had traditionally made low-budget second features. Its release was undermined by the studio's growing financial problems which led to its eventual closure in 1959.
