The British Aerospace ATP (Advanced Turbo-Prop) was an airliner produced by British Aerospace, introduced in the 1980s as an evolution of the Hawker Siddeley HS 748. The fuel crisis and increasing worries about aircraft noise led business planners at British Aerospace to believe that there was a market for a short-range, low-noise, fuel-efficient turboprop aircraft. By the time it entered the market, the segment was already well represented by designs such as the de Havilland Canada Dash 8 and ATR 42, and production was ended after only 64 examples.

The airframe of the HS 748 was redesigned with a lengthened 26.01 metres (85.3 ft) fuselage and a 30.62 metres (100.5 ft) wing span. Minor modifications were made to the nose and tail shapes; and smaller windows on a shorter pitch than the 748's were used. The 748's twin Rolls-Royce Dart engines were replaced with Pratt & Whitney Canada PW126 fuel efficient engines. A custom-designed, slow-turning, six-blade propeller was developed by Hamilton Standard.

The aircraft first flew in August 1986 and entered service with British Midland in 1988. The type has an advanced electronic flight instrument system flight deck, and has a good short-field performance. In addition to these virtues, it is also very quiet upon take off. The only U.S. operator of the ATP in scheduled passenger service was Air Wisconsin flying as United Express on behalf of United Airlines via a code sharing agreement.

In total 64 aircraft were assembled at BAe's Woodford and Prestwick facilities with the manufacture of the airframe and wings undertaken at Chadderton. Production ended at Prestwick in 1996. The ATP can accommodate between 64 and 72 passengers depending on the seat configuration.
