The Chilton D.W.1 is a British light sporting monoplane designed and built in the late 1930s by Chilton Aircraft at Hungerford, Berkshire.

The Chilton D.W.1 was designed and built on the Chilton Lodge estate at Leverton near Hungerford in Berkshire in early 1937 by two ex D.H. Technical School students who formed Chilton Aircraft Limited for the purpose designing light aircraft. The aircraft was intended to be cheap to build and operate, yet have an exceptional performance on low power. This was derived from its aerodynamically clean design with an all-wood airframe with plywood skin. Only the control surfaces and the trailing edge of the wing behind the rear spar were fabric covered. The wing also carried trailing edge split flaps. The undercarriage was enclosed in trouser fairings and a cabin top could be fitted.
