The Lippisch P.20 was a proposed World War II German fighter aircraft.

The design was the final one by Alexander Lippisch whilst working for the Messerschmitt company.

The aircraft was externally similar to the Me 163 upon which it was based, although the P.20 was in fact a new design sharing only a few parts with the Me 163.

The fuselage was deepened accommodating a single Jumo 004 turbojet fed by a low mounted nose intake.

The cockpit was moved further aft and upwards leaving room for two MK 108 autocannons and the nose wheel.
