The AEC Swift was a rear-engined step entrance single-decker bus chassis manufactured by AEC between 1964 and 1980.^[1] The chassis design was closely related to the Leyland Panther. It was available in 33-foot (10 m) and 36-foot (11 m) lengths, with an AEC AH505 or AH691 engine.^[2]

The design was suitable for driver-only operation which helped bus operators to relieve the problems of labour shortages and high costs, and became one of the alternatives to the British double-decker buses which could only be operated by a driver and conductor, such as the London AEC Routemaster or Bristol Lodekka, as British legislation prevented driver-only operation of double-decker buses until the late 1960s.
