The Airco DH.3 was a British bomber aircraft of the First World War. The DH.3 was designed in 1916 as a long-range day bomber by Geoffrey de Havilland, chief designer at the Aircraft Manufacturing Company. It was a large biplane with wide-span three-bay wings, slender fuselage, and a curved rudder. It was powered by two 120 hp (89 kW) Beardmore engines, mounted as pushers between the wings. In addition to tailskid landing gear, two wheels were placed beneath the nose to prevent bumping.

A second prototype, designated DH.3A, was built with more powerful (160 hp/119 kW) Beardmore engines, and the War Office placed a production order for 50. This order was cancelled, however, before any could be completed, because strategic bombing was not thought to be worthwhile, and twin-engined bombers were claimed to be impracticable. The two prototypes were scrapped in 1917.
The DH.10 was a development of the DH.3 which first flew in March 1918, but was too late to see squadron service during the war.
