SS El Sol was a cargo ship built in 1910 for the Morgan Line, a subsidiary of the Southern Pacific Company. During World War I, she was known as USAT El Sol in service with the United States Army and as USS El Sol (ID-4505) in service with the United States Navy. At the end of war, she reverted to her original name of SS El Sol. El Sol returned to the Morgan Line in 1919 and sailed with them until March 1927, when she sank in New York Harbor after colliding with Sac City of the American Diamond Line. A portion of the ship's cargo was salvaged but the ship was scrapped later in the year.
