Wikipedia says that Adding cheese to hamburgers became popular in the late-1920s to mid-1930s, and there are several competing claims as to who created the first cheeseburger. Lionel Sternberger is reputed to have introduced the cheeseburger in 1926 at the age of 16 when he was working as a fry cook at his father's Pasadena, California sandwich shop, "The Rite Spot", and "experimentally dropped a slab of American cheese on a sizzling hamburger."

However, Kentucky claims that a restaurant in Louisville created the first cheeseburger in 1934. A Denver drive-in has also claimed to have invented the first cheeseburger in 1935 and even have both a 1944 court order and trademark.

Common cheeses used for topping are American, Swiss, and other meltable cheeses.

Sometimes the cheese is inside the burger rather than above it. This type of burger is known as a 'Jucy Lucy'.
