SS Capella is an Algol class vehicle cargo ship that is currently maintained by the United States Maritime Administration as part of the Military Sealift Command's Ready Reserve Force (RRF). She was built as a high speed container ship by Rotterdamsche D.D.Mij N.V. in Rotterdam, Netherlands, hull no. 330, for Sea-Land Service, Inc. and named SS Sea-Land McLean, USCG ON 540413, IMO 7223508, after Sea-Land's founder Malcom McLean. Due to her high operating cost, she was sold to the United States Navy on 16 April 1982 as USNS Capella (T-AK-293).

Capella is the brightest star in the northern constellation of Auriga. It has the Bayer designation α Aurigae, which is Latinised to Alpha Aurigae and abbreviated Alpha Aur or α Aur. Capella is the sixth-brightest star in the night sky, and the third-brightest in the northern celestial hemisphere after Arcturus and Vega. A prominent object in the northern winter sky, it is circumpolar to observers north of 44°N. Its name meaning "little goat" in Latin, Capella depicted the goat Amalthea that suckled Zeus in classical mythology. Capella is relatively close, at 42.9 light-years (13.2 pc) from the Sun. It is one of the brightest X-ray sources in the sky, thought to come primarily from the corona of Capella Aa.
