We only included a deals if it was at a national or large regional fast food chain. We didn’t include any deals at local restaurants. Not that there aren’t good deals there, but that would just make this post too long.

However, I will give a quick shout out to the Union Gap Burger Trail in Union Gap, Washington. We went to the small town last year and ate burgers all around town. I’m not sure if any of those restaurants are offering National Cheeseburger Day deals, but it was fun to eat at them.

National Cheeseburger Day: Frequently Asked Questions

When is National Cheeseburger Day?

National Cheeseburger Day is celebrated annually on September 18th.

When is National Burger Month?

May is National Burger Month. And National Hamburger Day is celebrated on May 28th every year. National Cheeseburger Day is its own celebration.

Why do we celebrate National Cheeseburger Day?

The origin of the cheeseburger is rooted in a little bit of folklore. The story is that 16-year-old Lionel Sternberger was working at his father’s restaurant in Pasadena, California and added cheese to a burger — 26 years after the burger was created in America.

This is where the story veers into two camps. One says Lionel decided on a whim to throw a piece of cheese on top of a burger that was frying. The other story says a homeless man was passing by the restaurant and told Lionel to add a piece of cheese. Either way, Lionel added cheese to a burger and we’re all better for it.

As for why there’s a celebration of National Cheeseburger Day, that’s more so restaurants can cater to burger fans. It is an unofficial holiday, so there isn’t an official start or official proclamation.
