Dunkin', also known as Dunkin' Donuts, is an American multinational coffee and doughnut company. It was founded by William Rosenberg in Quincy, Massachusetts, in 1950. The chain was acquired by Baskin-Robbins' holding company Allied Domecq in 1990; its acquisition of the Mister Donut chain and the conversion of that chain to Dunkin' Donuts facilitated the brand's growth in North America that year. Dunkin' and Baskin-Robbins eventually became subsidiaries of Dunkin' Brands, headquartered in Canton, Massachusetts, in 2004, until being purchased by Inspire Brands on December 15, 2020. The chain began rebranding as a "beverage-led company", and was renamed Dunkin', in January 2019; while stores in the U.S. began using the new name, the rebranding will eventually be rolled out to all of its international stores.
