National Hamburger Day 2026 falls on Wednesday, May 28, and burger chains are marking it with a wide spread of discounts that run from one-day specials to offers that last through the weekend. The deals include a free hamburger for Burger King Royal Perks members with a $3+ online or app purchase, a buy-one-get-one offer at Carl’s Jr. and Hardee’s, and limited-time price cuts at restaurants from Charlotte to Utah.
Bad Daddy’s Burger Bar is selling its BD’s All-American Burger with a classic side for $10 on May 28. Big Buns rewards members can get a free Classic Burger with any purchase through May 31 in stores and online, while Bobby’s Burgers is offering a Crunchburger for $5.28 on May 28 at the Charlotte location and both Utah locations. Checkers & Rally’s is also giving customers a buy one, get one free deal on Classic Burgers that day.
The rest of the lineup stretches across dining rooms, drive-thrus and apps. Carl’s Jr. rewards members can buy one Famous Star burger and get a second for one cent at participating restaurants on May 28, using a single-use offer in the chain’s app, website or in restaurant, and the deal cannot be combined with other discounts. Hardee’s is running the same Famous Star promotion under the same restrictions. Del Taco rewards members have through May 30 to claim a buy one, get one free offer on Double Del Cheeseburgers, but orders must be placed in the app or on the chain’s website at participating locations.
Eddie Merlot’s is leaning into a more upscale version of the holiday, offering the Eddie’s Prime Cheeseburger + Housemade Potato Chips for $15 on May 28 for online takeout or delivery, or an Eddie’s Prime Cheeseburger for $15 during happy hour from 4 to 6:30 p.m. for dine-in guests. Farmer Boys VIF members can order a $3.99 Big Cheese Cheeseburger in the chain’s app, Fatburger is offering half off burgers with the purchase of a Pepsi, Firebirds Wood Fired Grill is listing its Smashburger on the Perfect Pair Menu for $14.95, and Good Times is selling a Deluxe Cheeseburger for $2.99 while dining in. Hard Rock Cafe is rounding things out with deals on Classic Smashed Burgers from 3 to 6 p.m. local time.
The pattern is clear: the best prices are usually tied to a rewards account, an app download or an online order, and the most aggressive offers are clustered on Wednesday itself. That makes May 28 the day to watch for anyone chasing a burger bargain, especially because some of the sharpest discounts disappear after a single meal period while others linger only a few more days.
