Estrella was a paddle steamship built by Samuda Brothers in London in 1853 for the Magdalena Steam Navigation Company's commercial services in present-day Colombia. In 1862 she was sold to United States owners and briefly used as a Union Army transport before being acquired by the Union Navy. She served as the armed steamship USS Estrella during the remainder of the American Civil War, carrying three heavy guns as well as two howitzers for shore bombardment.
