Dunkin' Donuts, trading as Dunkin' since 2019, is an American multinational coffee and donut company, as well as a quick service restaurant. It was founded by Bill Rosenberg (1916–2002) in Quincy, Massachusetts, in 1950. The chain was acquired by Baskin-Robbins' 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 company intends to roll out the rebranding to all of its international stores eventually.
With approximately 12,900 locations in 42 countries, Dunkin' is one of the largest coffee shop and donut shop chains in the world. In addition to various varieties of coffee and donuts, products sold include bagels, breakfast sandwiches, muffins, and donut holes branded as Munchkins.
