The McDouble is a hamburger sold by the fast-food restaurant chain McDonald's. It is a variation on the double cheeseburger, with only one slice of cheese placed between the two beef patties. It was introduced in 1997. It is one of the cheapest products sold by the company, and for this reason is often included in the chain's budget menus. The burger is almost identical to a Double Cheeseburger, except for the extra slice of cheese in the cheeseburger.
