Food holidays come and go, and most of them are small talk. National Cheeseburger Day is not one of them. This year, the big chains are lining up actual deals, from free burgers to canceled delivery fees, and the best part is that none of them require you to be a burger expert to enjoy.

What’s On the Menu

The deal roundup runs from Sept. 18, and the list includes almost every major fast-food chain you can name. Here’s the quick version:

  • McDonald’s is giving MyMcDonald’s Rewards members a free Double Cheeseburger with any $1 in-app purchase.
  • Burger King’s Royal Perks members get a free Bacon Cheeseburger with a $3 minimum purchase in the BK app.
  • Smashburger members can grab any single Smash burger for $1 — Classic, Bacon Stack, Truffle Mushroom — when ordering in-app or online.
  • Wendy’s Rewards members can add a Dave’s Single Cheeseburger for $1.99 to any order on Sept. 18.
  • Five Guys is running a BOGOBURGER promotion: buy any burger, get a second free with the promo code in the app or on the website.
  • Shake Shack is doing a $5 single ShackBurger or single Cheeseburger with any purchase, using the code BURGERDAY in the Shack App, on the website, and at in-store kiosks.
  • Dairy Queen is giving a free single Original Cheeseburger Stackburger with any $1+ app order running through Sept. 18.
  • Sonic is selling a Jr Double Cheeseburger for $1.99 when you order in-store or via the Sonic app.
  • Grubhub is canceling delivery and service fees on restaurant orders of $50+ on Sept. 18, plus a Burger King Whopper Jr. buy-one-get-one-free deal and a Wendy’s Baconator on orders of $20+.

The Deals Worth Noticing

Not all of these deals are created equal. Some are better for regular customers, some are better for one-offs, and some are just plain silly. The standout is the Grubhub cancellation, which applies to orders from multiple restaurants at once.

The free-burger offers are mostly limited to loyalty-program members, which means you need to be signed up ahead of time. That’s a small friction, but it’s the kind of thing that turns a casual impulse into a planned trip.

The five-dollar ShackBurger at Shake Shack is a solid value for anyone near one. The $1 Smashburger is a steal for anyone who eats at home.

Why This One Works

National Cheeseburger Day isn’t the first food holiday of the season, but it’s the one with the clearest payoff. The deals are immediate, the food is familiar, and the date is set. That combination means people will actually use these offers.

The fact that so many chains are participating is telling. Fast food is a competitive business, and the holiday draws attention across the board. Everyone gets a bigger audience, and everyone gets a reason to order.

For now, it’s just a good excuse to eat a burger that costs less than usual.
