Florenceville-Bristol is a former town in the northwestern part of Carleton County, New Brunswick, Canada along the Saint John River. It held town status prior to 2023 and is now part of the town of Carleton North.

Florenceville was originally known as Buttermilk Creek. In 1855 it was renamed Florenceville to honour Florence Nightingale, the famous Crimean War nurse. Florenceville was on the west side of the Saint John River and there the first post office and commercial section of the village was situated. In later years East Florenceville, previously known as Buckwheat Flats, became the commercial centre with five grocery stores and several other small businesses. There is a small strip mall along with several convenience stores and restaurants. The former village of Bristol is located on the Saint John River, in Carleton County, New Brunswick, Canada, approximately 5 kilometres north of Florenceville. It was named after the city of Bristol, England. The name replaced Kent Station in the 1880s.

Present-day Bristol was the site of a battle between Micmac and Maliseet peoples. The area was originally named Shiktehawk, from the Maliseet for "where he killed him". The name was changed when the New Brunswick Railway was constructed and railway officials were unable to pronounce the name correctly. Bristol is located where the Big Shiktehawk and Little Shiktehawk Streams empty into the Saint John River. This was an important stopping point for Native peoples as it was the start of the cross province route. They would canoe up the Big Shiktehawk Stream to Divide where they would portage a short distance to the Miramichi River and make their way to the eastern coast of New Brunswick.

On 1 January 2023, Florenceville-Bristol amalgamated with Bath, Centreville and all or part of nine local service districts to form the new town of Carleton North. The community's name remains in official use.
