The first USS Sappho (ID-1427) was a United States Navy ferry transport in commission from 1918 to 1919.

Sappho was assigned to the 4th Naval District for local transport duty, providing transportation between the Philadelphia Navy Yard in Philadelphia, Pennsylvania, and nearby ports in New York and New Jersey.

Five days after Sappho was commissioned, SS Delaware accidentally rammed her on 25 August 1918.

Repairs were complete by 20 October 1918, allowing Sappho to resume transport service.

Sappho was decommissioned at Philadelphia on 18 February 1919, and returned to her owner the same day.
