Martin-Baker Aircraft Company Limited is a British manufacturer of ejection seats and safety-related equipment for aviation. The company was originally an aircraft manufacturer before becoming a pioneer in the field of ejection seats. The company's headquarters are in Higher Denham, Buckinghamshire, England, with other sites in France, Italy and the United States.

In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft.
