USS Capricornus (AKA-57/LKA-57) was an Andromeda-class attack cargo ship named after the zodiacal constellation Capricornus.

The Andromeda-class attack cargo ships were a class of amphibious cargo ship built by Federal Shipbuilding & Drydock Co. in Kearny, New Jersey and Moore Dry Dock Co., in Oakland, California during World War II. Like all attack cargo ships, they were designed to carry combat loaded military cargo and landing craft, and to use the latter to land weapons, supplies, and troops on enemy shores during amphibious operations.
