The Sopwith Triplane was a British single seat fighter aircraft designed and manufactured by the Sopwith Aviation Company. During the First World War it was built in comparatively small numbers and was withdrawn from active service as Sopwith Camels arrived in the latter half of 1917. Surviving aircraft continued to serve as operational trainers until the end of World War One.
