USS Christabel (SP-162) was a civilian steam yacht that was built in Glasgow in 1893 for a Scottish industrialist. She had an American owner by 1910, served as a United States Navy patrol ship in the latter part of the First World War, and afterward was returned to US civilian service. The US Navy bought her in 1917, had her fitted out as a warship, and used her on patrol duty in the North Atlantic. She served with honor as a section patrol craft, surviving an attack on a German U-boat. After the war she was briefly a training ship, before being decommissioned and sold in 1919.
