Celebrate International Hamburger Day with Wendy’s Around the World

This International Hamburger Day, May 28, we’re celebrating a fan-favorite that’s been part of Wendy’s story since day one: our square hamburgers.  

First introduced in 1969, Wendy’s original hamburger set a new standard: fresh beef*, made-to-order and served just the way you like it as a single, double or triple. More than five decades later, that same commitment continues to define every hamburger we serve. 

Today, Wendy’s restaurants around the world are bringing that commitment to life in new and exciting ways. From bold, limited-time offerings to locally inspired creations, our menus reflect the flavors our fans love while staying true to what makes Wendy’s, Wendy’s. It’s all part of our ambition to be Globally Great, Locally Loved. 

No matter where you enjoy Wendy’s, one thing never changes: square hamburgers, made to order and served with pride. It’s a commitment you can taste in every bite, in every market, and in every Wendy’s restaurant around the world. 

Explore some of the standout Wendy’s square hamburgers making waves around the world: 

Mexico: Crunchy Jalapeño Dip 

Wendy’s Mexico is turning up the heat with the Crunchy Jalapeño Dip hamburger. Available for a limited time beginning June 9, 2026, this masterpiece starts with a 100% beef patty layered with crunchy tortilla chips, jalapeños, onions, spicy pepper mayo and melted cheese, all served on a toasted bun. A side of spicy cheddar cheese sauce lets fans customize every bite. 

Japan: Truffle & Mozzarella Baconator®  

In Japan, the Truffle & Mozzarella Baconator is a new fan-favorite available now, featuring a savory sauce made with chopped black truffles and fragrant white truffle oil. Paired with rich, creamy mozzarella cheese and crispy, flavorful bacon, this indulgent combination enhances the bold taste of Wendy’s square 100% beef patty.  

United States: Dave’s Single®  

In the U.S., the Dave’s Single remains a true original. Named after Wendy’s founder, Dave Thomas, the Dave’s Single starts with a quarter pound** of fresh beef topped with American cheese, crisp lettuce, tomato, pickles, onion, ketchup, mustard and mayonnaise all on a toasted potato bun. It’s a simple, satisfying cheeseburger made the way it was meant to be – hot, juicy and made to order with fresh ingredients, because that’s what Dave would do. 

Canada: Bacon Portabella Mushroom Melt  

Canada’s hamburger spotlight lands on the Bacon Portabella Mushroom Melt, better known (and loved) by Wendy’s fans as the BPMM. Celebrating 10 years on our menu, the BPMM features fresh 100% Canadian beef, Applewood smoked bacon, savoury portabella mushrooms, and a rich, melty cheddar cheese sauce. The BPMM delivers premium indulgence in a way only Wendy’s could - unapologetically craveable.  

United Kingdom: Jr. Bacon Cheeseburger 

Across the pond, celebrate this International Hamburger Day with a free Jr. Bacon Cheeseburger (JBC) with purchase in the Wendy’s UK mobile app***. The JBC, as fans lovingly call it, is made to order with fresh beef, Applewood smoked bacon, American cheese, and Heinz mayo with your choice of crisp lettuce and tomato. It's a favourite of bacon lovers everywhere! 

Latin America & Caribbean (LAC): Big Dipper 

Currently available throughout our LAC region, the Big Dipper delivers bold flavor with a fun, interactive twist. It features a 100% beef patty topped with crunchy tortilla chips, tomato, onions, smoky pepper mayo and melted cheese, all served on a toasted bun with a side of cheese sauce for dipping. The result is a craveable, playful culinary experience. 

One Wendy’s, Many Ways to Hamburger 

From spicy dips and crunchy toppings to mushroom‑forward classics and the iconic Dave’s Single, International Hamburger Day is a reminder that while Wendy’s hamburgers start with the same fresh foundation, how they come to life around the world is uniquely local, without ever cutting corners on quality, freshness and taste.
