What was the first McDonald's product to use the name Big Mac?

The first McDonald’s product to use the name Big Mac was the Big Mac hamburger.

McDonald’s introduced the sandwich in 1967 at a restaurant in Uniontown, Pennsylvania, operated by franchisee Jim Delligatti. It used two beef patties, a middle slice of bread, lettuce, cheese, pickles, onions, and the sauce later strongly associated with the sandwich. The product was designed to provide a larger, more substantial option than McDonald’s standard hamburger.

The name “Big Mac” became an important branding asset because it was short, memorable, and easy to use in advertising. The sandwich’s distinctive three-part bun and stacked construction also made it visually recognizable in menus and promotions.

A common confusion is treating “Big Mac” as the name of the sauce or a meal combination. Those are associated with the sandwich, but the trademarked product name refers to the hamburger itself. The Big Mac later became one of McDonald’s signature menu items worldwide.
