Burger King National Cheeseburger Day 2025: Free Deals, Perks Week Offers and Everything You Need to Know

If you love a good deal almost as much as you love a great burger, then Burger King National Cheeseburger Day is the event you have been waiting for all year. Every September 18, the whole country comes together to celebrate one of America’s most iconic foods — the cheeseburger. And when it comes to making this day special, Burger King does not just show up. They go all out with a full week of free food, daily deals, and exclusive offers that only get better every single year.

In 2025, Burger King launched its biggest National Cheeseburger Day celebration yet. From a free Bacon Cheeseburger on September 18 to a full Cheeseburger Perks Week running September 15 through September 21, this guide covers everything you need to know so you never miss a single BK deal again.

What Is National Cheeseburger Day and Why Does It Matter?

National Cheeseburger Day is celebrated every year on September 18. It is an unofficial but widely recognized American food holiday that pays tribute to the cheeseburger — that perfect combination of a juicy beef patty, melted cheese, and classic toppings nestled inside a soft bun. From fast food giants to sit-down restaurants, businesses across the country use this day as a reason to fire up the grill and reward their loyal customers with deals, discounts, and free food.

For Burger King fans specifically, this day has become one of the most exciting events of the year. BK consistently ranks among the top chains for the best National Cheeseburger Day deals, and in 2025 they delivered their most generous promotion yet. Rather than limiting the celebration to just one day, Burger King turned it into a full Cheeseburger Perks Week running from September 15 all the way through September 21, giving Royal Perks members a brand new free item every single day of the week.

Burger King National Cheeseburger Day 2025 — The Headline Deal

The star offer for Burger King National Cheeseburger Day 2025 was a free Bacon Cheeseburger with any purchase of $1 or more on Thursday September 18. That means for as little as a fountain drink or a small fries, you walked away with a free Bacon Cheeseburger added to your meal — one of BK’s most popular menu items featuring a flame-grilled beef patty, crispy bacon, melted American cheese, ketchup, mustard, pickles, and onions on a sesame seed bun.

The deal was exclusively available through the BK app or at bk.com for Royal Perks members at participating locations. Customers had to activate the offer in the Offers tab before placing their order. The offer was single-use and — importantly — not available through third-party delivery apps like Uber Eats or DoorDash. You had to order directly through BK’s own channels or visit in person.

Full Burger King Cheeseburger Perks Week 2025 — Daily Deal Schedule

What made Burger King’s National Cheeseburger Day 2025 truly exceptional was that BK did not stop at just one day of deals. The chain ran a full Cheeseburger Perks Week starting September 15 and running through September 21. Every single day brought a brand new free item for Royal Perks members with a minimum $1 purchase. Here is the complete confirmed daily schedule based on research from multiple sources including Today.com, Atlanta on the Cheap, and Hip2Save:

Monday September 15 — Free Hamburger

The week kicked off on Monday September 15 with a free Hamburger for Royal Perks members with any $1 or more purchase. A classic BK flame-grilled beef patty with ketchup, mustard, pickles, and onions — simple, satisfying, and completely free. A great way to start a week of deals.

Tuesday September 16 — Free Cini Minis

On Tuesday September 16, BK switched things up with a free order of Cini Minis with any $1 or more purchase. These warm cinnamon-glazed mini rolls are one of BK’s most loved breakfast items. Getting them free with your morning coffee or any small purchase made for a perfect start to the day.

Wednesday September 17 — Free Croissan’wich

Wednesday September 17 brought a free Croissan’wich with any $1 or more purchase. Burger King’s iconic breakfast sandwich on a warm flaky croissant with egg, cheese, and your choice of protein is always a fan favourite. Getting it free the day before the big National Cheeseburger Day event made the build-up even more exciting.

Thursday September 18 — Free Bacon Cheeseburger (National Cheeseburger Day!)

The main event. On National Cheeseburger Day September 18, 2025, Royal Perks members scored a free Bacon Cheeseburger with any $1 or more purchase.

Thousands of BK fans across the country flooded the app and visited their local Burger King to take advantage of what was genuinely one of the best fast food deals of the year.

Friday September 19 — Free Whopper Jr.

The celebration continued on Friday September 19 with a free Whopper Jr. with any $1 or more purchase.

Getting it free the day after National Cheeseburger Day was a brilliant bonus for loyal customers.

Saturday September 20 — Free Cheeseburger

On Saturday September 20, Royal Perks members could score a free classic Cheeseburger with any $1 or more purchase.

How to Claim Your Burger King National Cheeseburger Day Deal Step by Step

Claiming any of these Burger King National Cheeseburger Day deals is straightforward once you understand how the Royal Perks system works. Here is exactly what you need to do:

1. Download the BK app from the App Store or Google Play — it is completely free

Other National Cheeseburger Day 2025 Deals Worth Knowing About

While Burger King’s National Cheeseburger Day offer was among the strongest of 2025, several other major chains also jumped in with their own deals on September 18. Here is a look at the highlights from around the industry:

McDonald’s — 50 Cent Double Cheeseburger

McDonald’s had one of the cheapest deals of the day. App users could get a Double Cheeseburger for just 50 cents on September 18 at participating locations. A single-use app offer that provided incredible value for fans of the Golden Arches.

Wendy’s — 1 Cent Jr. Bacon Cheeseburger

Wendy’s went almost completely free with a 1 cent Jr. Bacon Cheeseburger with any in-app purchase from September 18 through September 22. Effectively free, this made Wendy’s one of the strongest competitors to BK’s deal on the day.

Dairy Queen — Free Double Cheeseburger Stackburger

DQ Rewards members scored a free Double Original Cheeseburger Stackburger with any app or online order of $1 or more. The promotion ran from September 15 through 19 and was open to both new and existing DQ Rewards members — a strong multi-day deal to match BK’s Perks Week approach.

Applebee’s offered one of three classic handcrafted burgers with a side of fries for just $8.99. No promo code required and the offer was valid for dine-in, to-go, online, and app orders — great for those who wanted a proper sit-down burger meal on the holiday.

Why Does Burger King Go So Big for National Cheeseburger Day Every Year?

You might wonder why Burger King gives away so much free food around National Cheeseburger Day. The answer is smart business strategy. Promotions like Cheeseburger Perks Week serve several important purposes that make them well worth it for BK.

First, they drive massive app downloads and Royal Perks sign-ups. Since all deals require the BK app, customers who never downloaded it before are highly motivated to sign up specifically to claim their free cheeseburger. Once they are in the Royal Perks ecosystem, they continue engaging with BK’s deals long after the holiday is over — meaning one free burger today drives repeat visits and real revenue for months.

Second, the free item deals all require a minimum $1 purchase. In practice, most customers spend much more than $1. Someone coming in for a free Bacon Cheeseburger almost always adds fries, a drink, or dessert to their order. So while BK is giving away one item, they are generating solid revenue from everything else in the basket at the same time.

Third, it creates enormous social media buzz and organic marketing. When millions of BK fans share their free cheeseburger photos and experiences online, the brand gets massive exposure at virtually zero additional advertising cost. This word-of-mouth effect has helped Burger King build one of the most engaged fast food loyalty communities in the industry.
