National Coffee Day 2026 is Tuesday, September 29. There are two confirmed national coffee offers worth planning around right now, and both have a purchase requirement. That little detail is how a “free coffee” run becomes a confusing receipt.
Confirmed National Coffee Day deals for 2026
Dunkin’: free medium coffee with an app purchase
Who: Dunkin’ Rewards members. When: September 29. How: Make any purchase through the Dunkin’ app at a participating U.S. store to get a free medium hot or iced coffee. It is single-use per member and excludes Cold Brew and hot espresso beverages. Dunkin says it cannot be combined with another offer or coupon.
This is the September 29 offer from Dunkin’s official announcement. The September 24 JUST4U code was a separate promotion and has ended. We have the L.L.Bean merch details and Dunkin’s app terms here.
Krispy Kreme: free small or medium coffee with a purchase
Who: Guests at participating U.S. Krispy Kreme shops. When: September 29 only. How: Buy something in a shop and get one free small or medium hot or iced coffee. The offer is in-shop only, limited to one per guest, and excludes specialty and frozen drinks. It does not apply at grocery or convenience stores that sell Krispy Kreme products.
Krispy Kreme lists the terms on its official National Coffee Day page, which also has a participating-shop lookup. Check that before you drive across town.
The doughnut deal is separate
Through September 29, Krispy Kreme is also offering an Original Glazed Coffee Flavored dozen—or a regular Original Glazed dozen—for $5 when you buy a dozen at regular price at participating U.S. shops. For online pickup or delivery, the promo code is COFFEE. Limits and availability apply. That is a second-dozen deal, not a $5 dozen by itself; here are the coffee-flavored doughnut details.
What about Starbucks, McDonald’s, and the rest?
We have not found a verified 2026 National Coffee Day offer from those chains to put on this list as of September 27. A deal from 2021 or 2025 is not a 2026 deal. Check each company’s app or official promotions page as Tuesday gets closer; we will add offers when their terms are confirmed.
Checked September 27, 2026. Offers can vary by participating location and may change or run out. This article replaces our 2021 deal list, whose offers have expired.
