Barregarrow (Manx: Bayr Garroo) is a crossroad-centred settlement south of the village of Kirk Michael in the Isle of Man. Located between the twelfth and thirteenth milestones on the famous TT course, the crossroads is a landmark on the famous road racing course. The A3 (TT Course) and the C4 (Ballaleigh Road) converge at this point.

Located at the top of "Barregarroo hill" on the Douglas Road two miles south of Kirk Michael, Barregarrow is a famous geographical landmark on the Snaefell Mountain Course of the TT Road Races. The crossroads is the location of a Victorian postbox, a traditional red telephone box and one of the first Wesleyan Methodist chapels on the Island. Situated opposite the chapel is the former Methodist chapel hall and Sunday school, used in the 1990s and early 2000s as the premises of a welding company specialising in wrought iron gates. The building is now home to a seasonal carpentry firm primarily for storage.

The crossroads is closed during the TT fortnight in May/June of each year during practice and racing hours and a similar situation occurs during the August Manx Grand Prix. The crossroads serves as a convenient location for touring riders to retire during races prior to the high speed approach to Kirk Michael village two miles further on. The Isle of Man dog warden, a boarding kennels and camp-site are located at Cronk Aashen in Barregarrow and serves as a main spectator facility during the motorcycling periods on the Island.
