Roy Chadwick, CBE, FRSA, FRAeS (30 April 1893 – 23 August 1947) was an English aircraft design engineer for the Avro Company.

Chadwick attended St Clements Church School in Urmston, then studied at night school from 1907 to 1911 at the Manchester Municipal College of Technology whilst training as a draughtsman at the British Westinghouse Electrical Company in Trafford Park under George Edwin Bailey of Metropolitan-Vickers.

In 1939, production of Avro aircraft was moved to a new factory at Greengate in Chadderton, owned by BAE Systems until its closure in 2012.

Author Harald Penrose describes Chadwick in "British Aviation" as "Artistic with unbounded enthusiasm and unsparing energy, Roy Chadwick was a great designer of intuitive diagnostic ability rather than a scientist, yet like all great masters was in step with the tide of knowledge and contemporary outlook."

Chadwick died on 23 August 1947 in a crash during the takeoff of the prototype Avro Tudor 2 G-AGSU from Woodford Aerodrome,[2] in the vicinity of Shirfold Farm.

The A523 bypass around Poynton, which crosses the former Woodford Aerodrome runway, has been named Roy Chadwick Way in his honour.
