What is the name of Shake Shack’s signature hamburger?

Shake Shack’s signature hamburger is called the ShackBurger.

The ShackBurger began as the flagship burger of Shake Shack, the restaurant company that grew from a hot-dog cart in New York City’s Madison Square Park. The original permanent Shake Shack opened in the park in 2004, helping establish the brand’s modern fast-casual identity.

The burger is made with a beef patty, American cheese, lettuce, tomato, and ShackSauce on a potato bun. Shake Shack’s beef blend and the soft Martin’s potato roll are frequently mentioned as part of the sandwich’s recognizable format.

The name is sometimes confused with the Shack Stack, another Shake Shack menu item. The Shack Stack combines a cheeseburger with a fried mushroom-filled cheese crisp, while the ShackBurger is the chain’s standard signature hamburger.
