The Bristol Buckmaster was an advanced British training aircraft operated by the Royal Air Force during the 1950s.

By 1945, there was a serious gap in performance between the so-called advanced trainers in use – such as the Avro Anson, Airspeed Oxford, dual-control Bristol Blenheim and Lockheed Hudson – and the combat aircraft which the pilots would be expected to fly on graduation.

The Bristol company's response to Air Ministry Specification T.13/43[1] was the Type 166 which was based on the Buckingham with a new wider front fuselage to allow side-by-side seating for an instructor and trainee and room for a radio operator.

Blind flying instruction and instrument training could be undertaken, the normal crew complement being pilot, instructor and air signaller.
