National Cheeseburger Day lands on Friday, September 18, 2026, and restaurant chains across the country are marking the occasion with free burgers, deep discounts, and rewards-only giveaways. From major fast-food names to sit-down chains, this year’s lineup of national cheeseburger day deals gives burger lovers plenty of reasons to treat themselves without spending much at all.
Below is a complete roundup of confirmed offers, along with tips on how to claim them before they run out.
What Is National Cheeseburger Day?
National Cheeseburger Day is an unofficial food holiday celebrated every September 18. It exists specifically to honor the cheeseburger, distinct from National Burger Day, which falls on May 28 and celebrates burgers more broadly. Restaurants have embraced the day as a marketing moment, and most major burger chains now treat it as an annual tradition worth building offers around.
This year, the holiday falls on a Friday, which means many chains are extending their promotions into the weekend or running them across several days leading up to September 18.
Burger King’s Cheeseburger Day Week
Burger King is running its biggest push of the week around National Cheeseburger Day. The chain’s Royal Perks members can unlock a different app-exclusive deal every day from Monday, September 14, through Sunday, September 20, as part of its ongoing Perks Week promotion.
The daily lineup includes a free Rodeo Burger with a three-dollar minimum purchase on September 14, a buy-one-get-one-free Whopper Jr. on September 15, and a free Croissan’wich on September 16. On September 17, members can get a free hamburger with a qualifying purchase. The centerpiece deal lands on National Cheeseburger Day itself: a free Bacon Cheeseburger with a three-dollar minimum purchase on September 18. The week wraps up with a free four-piece chicken nugget order on September 19 and a free Original Chicken Sandwich on September 20.
All Burger King offers require Royal Perks membership and must be redeemed through the app or website.
McDonald’s National Cheeseburger Day Offer
McDonald’s is giving MyMcDonald’s Rewards members a free Double Cheeseburger on September 18. The offer requires a one-dollar minimum purchase and must be redeemed through the McDonald’s mobile app. As with most fast-food promotions tied to the holiday, participation may vary slightly by location, so checking the app ahead of time is worthwhile.
Dairy Queen’s Multi-Day Cheeseburger Deal
Dairy Queen is stretching its promotion across several days rather than limiting it to September 18 alone. DQ Rewards members can claim a free Single Original Cheeseburger Signature Stackburger with any app or online order of one dollar or more from September 14 through September 18. This gives customers a longer window to redeem the offer compared to many one-day-only deals.
Wendy’s, Sonic, and Carl’s Jr. Deals
Several other major chains are offering their own take on National Cheeseburger Day savings. Wendy’s is featuring a Dave’s Single for $1.99 through an in-app purchase, giving fans of the chain’s classic burger a simple discount without needing a rewards account tied to points.
Sonic is running a special discount on its Jr. Double Cheeseburger through the Sonic app, while Carl’s Jr. rewards members can find a half-price burger deal when paired with the purchase of an ice cream shake, available on both September 17 and September 18.
Checkers, Rally’s, and Farmer Boys
Checkers and Rally’s customers can order a Big Buford burger for three dollars at participating locations on September 17 and 18. The deal does not require a rewards membership, making it one of the more accessible offers on this list.
Farmer Boys is offering its Very Important Farmer loyalty members an exclusive $3.99 Big Cheese cheeseburger on National Cheeseburger Day, available through the chain’s loyalty app.
Sit-Down Restaurant Deals
Fast-food chains are not the only ones celebrating. Several full-service restaurants have built National Cheeseburger Day promotions into their menus as well.
Applebee’s is offering a Classic Burger or Classic Cheeseburger with fries for $8.99 on September 18, available for dine-in or to-go orders placed in-restaurant, online, or through the Applebee’s app. The deal does not apply to third-party delivery orders.
Buffalo Wild Wings is running a buy-one-get-one-free burger deal at participating locations on September 18. Customers who buy one regular-priced cheeseburger receive a second burger of equal or lesser value for free, though the offer excludes lunch combos and kids’ menu items and cannot be combined with other discounts.
Bad Daddy’s Burger Bar is giving dine-in guests the option to order a Jalapeno Business burger paired with a choice of fries, sweet potato fries, tots, or homemade chips as its National Cheeseburger Day feature.
Bobby’s Burgers by Bobby Flay is offering a Palace Classic Cheeseburger, fries, and a small fountain drink for $9.18 on September 18, available at select locations in Charlotte and Utah, both in the app and in-restaurant.
Denny’s is featuring a buy-one, get-one 50 percent off deal on its Diner QP burgers for the holiday.
Dog Haus is rewarding customers differently: rewards members who purchase a cheeseburger on September 18 will receive a coupon for a free cheeseburger to use on a future visit, rather than an instant discount.
Eddie Merlot’s is offering its Eddie’s Prime Cheeseburger as part of its online ordering promotion on September 18 as well.
Smashburger and Shake Shack
Smashburger’s SmashRewards members can get any Single Smashburger for just one dollar on September 18, making it one of the steepest discounts among national chains this year. Shake Shack is also expected to run a Cheeseburger Day offer on either its ShackBurger or standard Cheeseburger at participating locations, though customers should check the app for the specific terms in their area.
How to Make Sure You Don’t Miss Out
Because most of these national cheeseburger day deals are tied to rewards programs or mobile apps, a little preparation goes a long way. Downloading the apps for your preferred chains before September 18 and creating a rewards account in advance can prevent delays at checkout.
It is also worth double-checking participation at your local restaurant, since franchise-owned locations sometimes opt out of national promotions or apply slightly different terms. Offers may also have limited quantities per customer or per location, so arriving earlier in the day can help avoid disappointment if a deal runs out.
Finally, keep in mind that some deals, like Burger King’s Perks Week and Dairy Queen’s cheeseburger offer, start before September 18 itself. Reading the fine print on each promotion ensures you claim the right deal on the right day.
