The Pfalz D.XV was a German single seat fighter aircraft which was approved for production right at the end of World War I, too late to enter service.

The D.XV was last of the series of biplane fighters and notably different from their earlier aircraft, with both mainplanes clear of the fuselage and without flying wires.

[1] The D.XV had a 185 hp (138 kW) 6-cylinder water-cooled inline engine BMW IIIa with a rectangular radiator filling the upper nose above the drive-shaft of the two blade propeller.

Aft, the fuselage was rounded in cross-section with the single open cockpit behind the upper wing's trailing edge.

Nonetheless, several were built and finished, and there were 74 completed fuselages in the Pfalz works when these were inspected by the Allies in the autumn of 1919.
