USCGC Salvia (WLB-400) was a United States Coast Guard Iris-class buoy tender in commission from 1944 to 1991.

In May 1944, she was assigned to the 5th Coast Guard District and stationed in Portsmouth, Virginia, where she remained until the end of World War II in 1945.

After the war, Salvia was homeported in Mobile, Alabama, and continued to perform general ATON duties.

In April 1951 she was disabled in Calasieu Pass near Cameron, Louisiana, and was towed back to port by the cutter USCGC Tampa (WPG-164).

In December 1968, Salvia searched for survivors from the lost coastal buoy tender USCGC White Alder (WLM-541).

Renamed Brian Davis in memory of a local diver, she was scuttled on 24 July 2020 in southern Onslow Bay off Topsail Beach, North Carolina, about 15 nautical miles (28 km; 17 mi) from Topsail Inlet and 18 nautical miles (33 km; 21 mi) from Masonboro Inlet at 34°09.514′N 077°25.782′W / 34.158567°N 77.429700°W / 34.158567; -77.429700 (Brian Davis/USCGC Salvia), as a part of artificial reef project AR-368.
