Dunkin' Donuts LLC, also known as
Dunkin' and by the initials
DD, is an American multinational coffee and doughnut company, as well as a quick service restaurant. It was founded by Bill Rosenberg (1916â2002) in Quincy, Massachusetts, in 1950. The chain was acquired by Baskin-Robbins's holding company Allied Lyons 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.
