Three hospital ships of the United States Navy have borne the name
USS Mercy, in honor of the virtue of compassion (and owing to their purpose).
USS Mercy (AH-4), was built in 1907 as Saratoga and was commissioned Mercy (ID-1305) on 24 January 1918, before being re-designated AH-4 in 1920. She served in the Atlantic Fleet during World War I.
USNS Mercy (T-AH-19), was placed in service in 1986 and served during the Gulf War, as well as numerous Humanitarian Assistance Missions. She is currently in active service.
