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.
