The Focke-Wulf Triebflugel, or Triebflugeljager, literally meaning "thrust-wing hunter", was a German concept for an aircraft designed in 1944, during the final phase of World War II as a defense against the ever-increasing Allied bombing raids on central Germany. It was a vertical take-off and landing tail-sitter interceptor design for local defense of important factories or areas which had small or no airfields. The Triebflugel had only reached wind-tunnel testing when the Allied forces reached the production facilities. No complete prototype was ever built.
