Hamburgers go back to the late 1800s, when beef patties started showing up between buns at diners and food carts. Today, Americans eat around 50 billion burgers a year. That’s roughly three burgers a week per person. And while burgers hardly need a holiday to stay relevant, May 28 marks National Hamburger Day, an unofficial celebration of one of America’s favorite meals and where you can get sweet deals.

 Here are the best National Hamburger Day 2025 deals you can get.

Burger King

Royal Perks members get a free hamburger with any $1+ purchase on May 28. The deal must be activated in the app before ordering. You can also redeem a hamburger for 125 Crowns, half the usual points, through the end of May.

Wendy’s

Wendy’s is running one of the best deals of the week: a Jr. Bacon Cheeseburger for just one cent with any purchase made in the app. The offer is valid from May 28 through June 1, and it’s part of Wendy’s 100 Days of Savings promotion. You need to be a Rewards member, but there’s no minimum purchase requirement beyond that initial item — so even a drink counts.
