Patrol Boat, Riverine or PBR, is the United States Navy designation for a small rigid-hulled patrol boat used in the Vietnam War . In the Vietnam War, the Mobile Riverine Force (MRF) (after May 1967), initially designated Mekong Delta Mobile Afloat Force, and later the Riverines, were a joint US Army and US Navy force that comprised a substantial part of the Brown Water Navy.

For coastal duty the South Vietnamese Navy used larger seaworthy craft. These were replaced by newer U.S. Navy Swift Boats (PCF—Patrol Craft Fast, aluminum 50 footers) and United States Coast Guard Point-class cutters. By the late 1960s, the Swift Boat would commence operations alongside the PBRs in the inland waters, as well as maintaining operations along the coast line. Navy and Coast Guard ships assumed coastal duties.
