The Davis D-1 is an American light two-seat parasol-winged monoplane of the late 1920s.

The D-1 is a parasol-winged aircraft of mixed construction with a two-spar wing and a rectangular welded steel-tube fuselage, the whole being covered by fabric.

There are tandem open cockpits and it is fitted with a fixed tailwheel undercarriage which is attached by struts to the fuselage top and bottom.

In September 1930, Art Chester bought a Davis D-1-85 parasol, and flew it to victory in the 1930 National Air Races.

It was later owned by movie star Richard Arlen, and restored to become a Grand Champion antique.
