Find Your Free Doughnut on National Donut Day

National Donut Day is Friday and in honor of their big day, doughnut shops across the nation—including many in Maryland —will hand out free doughnuts to customers.

With many locations in the area, Dunkin' Donuts is on board with the holiday.

They say that they'll hand out one free doughnut of your choice "while supplies last" with the purchase of a beverage. (Could Dunkin' Donuts ever really run out of doughnuts?) Find your nearest store using their restaurant locator.

Here are a few locations in Prince George’s County:

• 15231 Hall Rd, Bowie
• 6101 Highbridge Rd, Bowie
• 6796 Laurel Bowie Rd, Bowie
• 7903 Annapolis Rd, Lanham

Duck’s Donuts, which just opened a Rockville location, will give customers one sugar doughnut for free on Friday, no purchase required. Claim your freebie at 1327 Rockville Pike, Rockville.

With fewer freestanding store locations, Krispy Kreme is also taking part.

The chain’s locations in Maryland are:

The holiday itself, always celebrated on the first Friday of June, was established in 1938 by the Chicago Salvation Army to honor women who served doughnuts to soldiers during World War I.

The Salvation Army this year is teaming up with baking company Entenmann's to help celebrate National Donut Day; Entenmann's will donate proceeds from sales and offer customers a chance to win free doughnuts for a year, by entering a contest on its Facebook page. Entenmann's doughnuts can be found at area grocery stores.
