Note: This is a sub-section of Westland Aircraft.

The Westland Wallace was a British two-seat, general-purpose biplane of the Royal Air Force, developed by Westland as a follow-on to their successful Wapiti. As the last of the interwar general purpose biplanes, it was used by a number of frontline and Auxiliary Air Force Squadrons.

Although the pace of aeronautical development caused its rapid replacement in frontline service, its useful life was extended into the Second World War with many being converted into target tugs and wireless trainers. In 1933 a Westland Wallace became the first aircraft to fly over Mount Everest, as part of the Houston Mount Everest Expedition.
