Template:EngvarB This compilation enumerates aircraft either designed by Geoffrey de Havilland or developed at the de Havilland Aircraft Company from its inception in 1920 until its acquisition and assimilation into the Hawker Siddeley Group in 1959.

Aircraft are catalogued according to the de Havilland model numbering system, which originated during de Havilland's tenure as chief designer at the Airco firm. Although Airco manufactured these airplanes, the design rights belonged to de HavillandTemplate:Fix/category, who maintained the numbering sequence upon founding his own enterprise. This sequence persisted through subsequent de Havilland company designs, regardless of whether de Havilland himself was directly involved. For instance, the DH.89 represents the eighty-ninth design attributed to de Havilland.

The projects DH.121 and DH.125, which were underway when de Havilland ceased to exist as an independent entity under Hawker Siddeley, preserved their original numbering and entered production as the Hawker Siddeley HS-121 Trident and the Hawker Siddeley HS.125 respectively.

This list excludes aircraft developed by de Havilland Canada and de Havilland Australia, which were established as subsidiaries of de Havilland.

A distinct listing covers earlier creations prior to the company's establishment, including his initial two family-funded biplanes, various models conceived at the HM Balloon Factory (later known as the Royal Aircraft Factory), and subsequent designs at The Aircraft Manufacturing Company Limited (Airco).

Designs before company establishment

These entries encompass Geoffrey de Havilland's aircraft conceived either independently or for other manufacturers.

Design number	Aircraft	First flight	Remarks
	Biplane No. 1	December 1909	A single-seat biplane constructed with financial support from his maternal grandfather. De Havilland devoted two years to its completion. Its maiden brief flight ended in a crash near Seven Barrows close to Litchfield, Hampshire in December 1909.
	Biplane No. 2	25 September 1910	A single-seat biplane featuring a pusher configuration, later designated as F.E.1. Following the loss of his first aircraft, he built this new biplane and conducted its initial flight from a meadow near Newbury in September 1910.
F.E.1	Biplane No. 2	25 September 1910	A single-seat pusher biplane that became known as the F.E.1. In December 1910, de Havilland joined HM Balloon Factory at Farnborough, which evolved into the Royal Aircraft Factory. He sold this second plane, which he used to teach himself flying, to his employer for £400. It was designated F.E.1, marking the first official Royal Aircraft Factory model number. Over the next three years, he was involved in designing several experimental aircraft at the factory. Until approximately 1913, designation letters indicated aircraft configurations inspired by French designers: S.E. = Santos Experimental (Canard or tail-first layout) B.E. = Blériot Experimental (Tractor or propeller-first layout) F.E. = Farman Experimental (Pusher or propeller behind pilot layout) From around 1913/14 onward, designations shifted to reflect intended operational roles. The B.S.1 of 1913 was an exception combining both systems: Blériot (tractor) Scout (fighter).
S.E.1	Santos Experimental 1 Royal Aircraft Factory	11 June 1911	An experimental research craft initially modeled on a Santos monoplane design but developed into a pusher biplane with prominent balanced fore-elevators resembling the Wright Flyer’s basic configuration but with a fully enclosed fuselage. It had ailerons on the upper wing and twin balanced rudders positioned behind the propeller, powered by a 60 hp (45 kW) E.N.V. Type F engine.
F.E.2	Farman Experimental 2 (Pusher type) Royal Aircraft Factory	18 August 1911	A two-seat pusher biplane designed for fighter/reconnaissance roles. It resembled a refined version of the F.E.1 without a front elevator and accommodated two crew members within a wooden and fabric nacelle. Powered by a 50 hp (37 kW) Gnome rotary engine.
B.E.1	Blériot Experimental 1 (Tractor type) Royal Aircraft Factory	4 December 1911	Two-seat tractor biplane trainer featuring two-bay parallel-chord unstaggered wings with rounded tips. Roll control was achieved through wing warping; it utilized a 60 hp (45 kW) water-cooled Wolseley engine.
B.E.2	Blériot Experimental 2 (Tractor type) Royal Aircraft Factory	1 February 1912	Two-seat tractor biplane serving as trainer/bomber. Similar to B.E.1 but powered by a 60 hp (45 kW) air-cooled V-8 Renault engine and equipped with equal-span wings.
B.S.1 / S.E.2	Blériot Scout 1 Scout Experimental 2 (Tractor type) Royal Aircraft Factory	March 1913	Single-seat scout tractor biplane named B.S.1 after Louis Blériot. It featured a wooden monocoque fuselage with circular cross-section and single-bay wings controlled laterally by wing warping. Equipped with a two-row, fourteen-cylinder Gnome rotary engine rated at 100 hp (75 kW).
DH.1	Airco DH.1	January 1915	Two-seat general-purpose fighter biplane. In December 1913, de Havilland became an inspector for the Aeronautical Inspection Directorate but grew dissatisfied with leaving design work behind at Royal Aircraft Factory. Consequently, in May 1914 he was appointed chief designer at The Aircraft Manufacturing Company Limited (Airco) in Hendon. He created numerous aircraft for Airco bearing his initials DH. Many of these designs were extensively utilized by the Royal Flying Corps and later Royal Air Force during World War I.
DH.2	Airco DH.2	1 June 1915	Single-seat pusher fighter biplane.
DH.3	Airco DH.3		Twin-engine long-range day bomber.
DH.4	Airco DH.4	August 1916	Two-seat day bomber biplane.
DH.5	Airco DH.5	October 1916	Single-seat fighter biplane.
DH.6	Airco DH.6	1916	Biplane used primarily for training purposes.
DH.7		Not constructed	Proposed single-seat tractor fighter powered by Rolls-Royce Falcon engine; project abandoned due to unavailability of engine
DH.8		Not constructed	Planned pusher fighter intended to mount a Coventry Ordnance Works gun; not built owing to delays in gun development and lack of specified engine
