USS Matsonia (ID-1589) was a transport for the United States Navy during World War I. Before and after her Navy service she was ocean liner SS Matsonia for the Matson Navigation Company. The liner was sold in 1937 to the Alaska Packers Association and renamed SS Etolin. Shortly before World War II, the ship was chartered by the United States Army as USAT Etolin. Transferred to the War Shipping Administration in 1946, Etolin was placed in the James River Reserve Fleet and ultimately scrapped in 1957.
