This is a list of aircraft produced or proposed by Geoffrey de Havilland or designed at the de Havilland Aircraft Company from its founding in 1920 until its purchase by (and integration into) the Hawker Siddeley Group in 1959.
The aircraft are ordered by de Havilland model number; the numbers started with de Havilland's employment at the Airco company as chief designer. Although Airco built the planes, their design was owned by de Havilland and when de Havilland started his own company, he continued the numbering. The numbering sequence continued for later designs of de Havilland's aircraft company, even if they were designed by a factory team with little input from de Havilland himself. The DH.89, for example, was the 89th de Havilland design.
The designs DH.121 and DH.125 which were under development when de Havilland lost its separate identity under Hawker Siddeley, retained their numbering and were produced as the Hawker Siddeley HS-121 Trident and the Hawker Siddeley HS.125.
The list does not include aircraft designed by de Havilland Canada or de Havilland Australia, founded as de Havilland subsidiaries.
These are designs by Geoffrey de Havilland while working for himself or for other manufacturers.

Number later allocated to a light single-engine civil biplane intended as DH.87 replacement. This was abandoned due to WWII. | ||

| DH.101 | Not built | High speed, high-altitude unarmed night intruder with Napier Sabre engines to Specification B.11/41 and based on the Mosquito.

| DH.110 | Sea Vixen | 26 September 1951 | Two-seat naval fighter | |
| DH.111 | Not built | Jet bomber based on Comet I to Specification B.35/46 proposed in May 1948. Despite not meeting the Specification, it represented the most advanced aircraft that could be produced with a certainty of success within a reasonable time scale. The Comet's wing and engines and tailplane were fitted to a thinner fuselage that could carry a single 10000 lb bomb or eighteen 1000 lb bombs and a crew of four. Pilot located under a bubble canopy offset to the left with the copilot on the right side and two radar navigators/bomb aimers behind the pilot facing to the rear. | ||

| DH.116 | Not built | Naval jet fighter to Specification N.114 powered by a Rolls-Royce RA.14 Avon jet engine with an estimated maximum speed of Mach 1.0 in level flight. Cockpit and fuselage were based on the Sea Venom with a new thin-section swept-back wing. Dropped in favor of the DH.110. | ||
| DH.117 | Not built | Submission to F.155T, designed with straight wing and to be powered by two de Havilland Gyron Junior turbojets and one de Havilland Spectre rocket. | ||
| DH.118 | Not built | Long-haul jet transport powered by four Rolls-Royce Conway jet engines. Designed as a Comet successor to carry 120 passengers on transatlantic and similar long-distance routes. Larger than the Comet but smaller than the Boeing 707, the DH.118 promised improved speed and increased range. Announced in the House of Commons on 24 October 1956, the aircraft was planned to commence operations in February 1962, but was abandoned in February 1957 in favor of the Vickers VC10. | ||
| DH.119 | Not built | High-speed short to medium range high-capacity airliner. Projected in 1956-1957, the DH.119 was based on Comet experience and intended to fulfill a BEA requirement. The aircraft sat 95 passengers over lengths of 1250 mi. Wings and tail surfaces were swept back 35° with four Rolls-Royce Avon jet engines mounted in pairs under the wing trailing edge. | ||
| DH.120 | Not built | Jet airliner similar to the DH.119, but to meet both BEA and BOAC requirements. | ||
| DH.121 | Hawker Siddeley Trident | 9 January 1962 | Three-engine jet airliner | |
| DH.122 | Not built | Proposed Trident variant to compete with the Vickers VC10. Number also used for a executive aircraft project at Christchurch powered by two Gnome engines to complement the DH.123. | ||
| DH.123 | Not built | Feederliner intended as a Dakota replacement. Powered by two de Havilland Gnome turboprops with a high-wing layout and a maximum capacity of 40 passengers or a payload of 7800 lb. Designed for economic operations over very short routes (e.g 200 mi), but with a full fuel load and payload reduced to 2400 lb, the range could be extended to 1610 mi. Abandoned due to competition with the HS.748 when de Havilland joined Hawker Siddeley. de Havilland turned to the DH.126 instead. | ||
| DH.124 | A series of design studies for a twin-engine jet airliner with BS.75 engines on the rear fuselage and a high-swept tail. The aircraft would seat 48 passengers with room forward for cargo. Similar in size to the Hunting H.107 project. | |||
| DH.125 | British Aerospace 125 initially "Jet Dragon" | 13 August 1962 | Medium corporate jet | |
| DH.126 | Not built | Twin jet-engine feederliner similar to the DH.125 but seating 26-32 passengers. Design put forward in May 1960, powered by two engines of 3500-4200 lb thrust range. Engines considered were the Rolls-Royce RB.173, de Havilland BS.92 and GE CF-700. | ||
| DH.127 | Not built | Proposed delta-winged strike fighter for Royal Navy as Blackburn Buccaneer replacement, early 1960s. Design featured two Rolls-Royce Spey engines with vectored thrust and two Rolls-Royce RB.108 lift jets in the nose to lower approach speed. Designation chosen to avoid confusion with the Hawker P.1127 that was later designated DH.128. |
