USCGC Bramble (WLB-392) is one of the 39 original 180-foot (55 m) seagoing buoy tenders built between 1942 and 1944 for the United States Coast Guard. In commission from 1944 until 2003 she saw service in Pacific, Caribbean and Atlantic waters as well as the Great Lakes. In 1947 Bramble was present at the Nuclear testing at Bikini Atoll and in 1957 a circumnavigation of North America involved a forced traverse of the Northwest Passage. After decommissioning in 2003 Bramble became a museum ship in Port Huron, Michigan. In 2018 she was sold to a private owner, who is preparing MV Bramble to repeat her historic 1957 circumnavigation of North America.

The USCG seagoing buoy tender is a type of United States Coast Guard Cutter used to service aids to navigation throughout the waters of the United States and wherever American shipping interests require. The U.S. Coast Guard has maintained a fleet of seagoing buoy tenders dating back to its origins in the U.S. Lighthouse Service (USLHS). These ships originally were designated with the hull classification symbol WAGL, but in 1965 the designation was changed to WLB, which is still used today.
