This is a list of notable hamburger restaurants . A hamburger is a sandwich consisting of one or more cooked patties of ground meat (usually beef) usually placed inside a sliced hamburger bun. Hamburgers are often served with lettuce, bacon, tomato, onion, pickles, cheese, and condiments such as mustard, mayonnaise, ketchup, and relish.

A fast-food restaurant, also known as a quick-service restaurant (QSR) within the industry, is a specific type of restaurant that serves fast-food cuisine and has minimal table service. The food served in fast-food restaurants is typically part of a "meat-sweet diet", offered from a limited menu, cooked in bulk in advance and kept hot, finished and packaged to order, and usually available for take away, though seating may be provided. Fast-food restaurants are typically part of a restaurant chain or franchise operation that provides standardized ingredients and/or partially prepared foods and supplies to each restaurant through controlled supply channels. The term "fast food" was recognized in a dictionary by Merriam–Webster in 1951.
