Founded in 1950 by William Rosenberg in Quincy, Massachusetts, Dunkin’ (originally known as Dunkin’ Donuts) is a globally dominant American fast-food icon recognized as one of the largest coffee and baked goods chains in the world. Operating under the famous slogan “America Runs on Dunkin'”, the brand underwent a major strategic rebrand in 2019, dropping “Donuts” from its name to reflect its modern evolution into a premium, beverage-led company. Today, while still deeply loved for its classic donuts and bite-sized Munchkins, Dunkin’ serves millions of customers daily across dozens of countries, driven by a massive, loyal following for its signature hot and iced coffees, cold brews, espresso drinks, and a popular line of breakfast sandwiches.
