A cheeseburger is a hamburger with cheese. Traditionally, the cheese is placed on top of the patty, but the burger can include many variations in structure, ingredients and composition. The term itself is a portmanteau of the words "cheese" and "hamburger." The cheese is usually sliced, and then added to the cooking hamburger patty shortly before the patty is completely cooked which allows the cheese to melt. Cheeseburgers are often served with lettuce, tomato, onion, pickles, mustard, mayonnaise or ketchup.

In fast food restaurants, the cheese used is typically processed cheese, but there are variations, such as cheddar, Swiss cheese, mozzarella, blue cheese and pepper jack. When cheese is added to a burger the nutritional value of the burger can be changed substantially. For example, a slice of Cheddar cheese can add 95 calories and 4.5 grams of saturated fat to a burger. Other types and amounts of cheese would have varying effects, depending on their nutritional content.

Adding cheese to hamburgers became popular in the mid-1920s to mid-1930s, and there are several competing claims as to who created the first cheeseburger. Lionel Sternberger is reputed to have invented the cheeseburger in the mid-1920s 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."
