USS Mauna Kea (AE-22) was a Suribachi-class ammunition ship of the United States Navy that was laid down at the Bethlehem-Sparrows Point Shipyard Inc., Sparrows Point, Maryland, on 6 May 1955; launched on 3 May 1956; sponsored by Mrs. Charles R. Brown; and commissioned on 30 March 1957, Captain Kenneth Loveland in command. The ship was decommissioned 30 June 1995 with over 38 years of active service. Mauna Kea was the oldest active ship in the Navy for a single week prior to being decommissioned.

The Suribachi-class ammunition ships was a class of two auxiliary vessels of the United States Navy in service from 1956 to 1995. They were among the first specialized underway replenishment ships built after World War II. The Nitro-class ammunition ships are sometimes considered part of this class. Both ships were decommissioned in the mid-1990s and were struck from the Naval Vessel Register in 1996. Both vessels were discarded in the 2000s.
