The Fieseler F 3 Wespe ("Wasp") was a German aircraft designed by Alexander Lippisch as the Delta IV and built by Fieseler. Lippisch later redesignated its variants as the Delta IVa and b, with the c variant being built as the DFS 39.

Little history of the aircraft remains due in part to destruction of records and documents during World War II.
