The Pfalz D.XII was a German fighter aircraft built by Pfalz Flugzeugwerke. Designed by Rudolph Gehringer as a successor to the Pfalz D.III, the D.XII entered service in significant numbers near the end of the First World War. It was the last Pfalz aircraft to see widespread service. Though the D.XII was an effective fighter aircraft, it was overshadowed by the highly successful Fokker D.VII.
In early 1918, the Idflieg (Inspektion der Fliegertruppen) distributed to German aircraft manufacturers a detailed engineering report on the SPAD S.VII, whose wing structure Idflieg considered to be well-designed. Pfalz accordingly produced several Pfalz D.III-derived prototypes with SPAD-type wings. These developed into the Pfalz D.XII. The new aircraft was powered by the 180 hp Mercedes D.IIIaü engine and continued the use of LFG-Roland's patented Wickelrumpf plywood-skinned monocoque fuselage construction. Unlike the earlier aircraft, the D.XII used a two-bay wing cellule. Furthermore, the flush wing radiator was replaced with a car-type radiator mounted in front of the engine.
