National Burger Day Deals Worth Leaving the House For
Free burgers, $1 burgers, BOGO burgers, and $5.28 steals are live today. I rounded up the biggest National Hamburger Day offers in one place so you can grab the best one before the apps get slammed or the promos disappear.
Fast heads-up: Most deals require the restaurant app or rewards account, and almost every chain says “participating locations only.” Check the app before you drive, because the best offers can be one-time use, online-only, or while supplies last.

Before you go burger hunting
A few quick answers will save readers from app frustration and wasted trips.
Is it National Burger Day or National Hamburger Day?
Most restaurants and news outlets are using National Hamburger Day for May 28, while many readers search for National Burger Day. The deals above apply to the May 28 burger holiday promotions.
Do I need the apps?
For many of the strongest deals, yes. Burger King, Dairy Queen, Sonic, Whataburger, Wayback, and several others either require rewards membership, app ordering, or an online account.
Can I stack these with coupons?
Usually no. Several chains specify that offers cannot be combined with other discounts or promotions. If the app rejects a code, remove other coupons first.
Will every location honor these deals?
Not always. Restaurant promos are often limited to participating locations, and some exclude airports, stadiums, travel plazas, arenas, or third-party delivery apps.
