The Handley Page H.P.39 was a wooden biplane design of the late 1920s. The aircraft was intended to compete in a competition proposed by the Daniel Guggenheim Fund for the Promotion of Aeronautics - the Safe Aircraft Competition. The original working name for the aircraft was the Guggenheim Competition Biplane, which was contracted to Gugnunc.

Only one example of the type was constructed, allotted civil registration G-AACN. The aircraft competed in the competition in 1929, but did not win. On return to the UK, the aircraft continued experimental flying, and was ultimately purchased by the Air Ministry, given registration K1908, and allocated to the Royal Aircraft Establishment for further testing. The aircraft was struck off in 1934, and is currently displayed in the Science Museum annex at Wroughton.
