Dunkin' Brands Group, Inc. was an American restaurant holding company that ran three chains of fast-food restaurants: Dunkin' Donuts, Mister Donut, and Baskin-Robbins. It was headquartered in Canton, Massachusetts. It was acquired by Inspire Brands in 2020.

Dunkin' Donuts, doing business 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.
