The HS 748, later known under the British Aerospace BAe-748 designation, is a twin-engine turboprop regional and utility aircraft developed by Avro and produced by Hawker Siddeley in the late 1950s and 1960s. It was designed to replace the venerable Douglas DC-3 and to serve short-haul routes with improved speed, payload, and modern systems.

Known for its rugged construction, high-wing layout, and reliable performance, the HS 748 was a favorite among regional airlines, military users, and developing nations due to its ability to operate from short, unpaved runways and its ease of maintenance in remote environments.
