Bulle (French: [byl] ; Arpitan: Bulo [ˈbylo] ) is a municipality in the district of Gruyère in the Canton of Fribourg in Switzerland. In January 2006 Bulle incorporated the formerly independent municipality of La Tour-de-Trême .

Bulle is first mentioned in the 9th century as Butulum. In 1200 it was mentioned as Bollo. The municipality was formerly known by its German name Boll; however, that name is no longer used.

Very little is known about the early history of the Bulle area.
