The BK Stacker sandwiches are a family of cheeseburgers sold by the international fast-food restaurant chain Burger King.

After assuming ownership, TPG's newly appointed management team began focusing menu development and advertising on a very narrow demographic group, young men aged 20–34 who routinely ate at fast food restaurants several times per month which the chain identified as the "super fan".

The Stacker line was part of a series of larger, more calorie-laden products introduced by the company to entice the super-fan into the chain's restaurants.

The characters were "Vin," played by Danny Woodburn, "the new guy," and various members of the "Stackers Union" construction team that work in a BK kitchen assembling the sandwiches.

As exemplified in the advertising campaign, part of the sandwich's concept revolves around not having vegetables like lettuce, onions, or tomatoes.
