The Heinkel He 343 was a quadjet bomber project designed by the German aircraft manufacturer Ernst Heinkel Flugzeugwerke during the final years of the Second World War. It was intended to perform aerial reconnaissance and fighter-bomber operations in addition to its use as a fast bomber.

The project commenced work in January 1944 as a new jet-powered bomber that emphasised flexibility in terms of mission role and engine fitout. Munitions were to be carried both externally and internally. Four variants of the He 343 were envisioned to perform bombing, reconnaissance, and direct fire support roles. The Government Air Ministry (Reichsluftfahrtministerium) quickly issued an initial order for 20 aircraft, which Heinkel worked on fulfilling. Despite lobbying efforts by the company's founder, Ernst Heinkel, to maintain the project, during late 1944, work was halted on the project and the order cancelled on account of Germany's deteriorating military situation necessitating the diversion of limited resources towards other programmes closer to production. Both design information and many of the components were recovered from Heinkel by the Soviet Union near the end of the conflict. The He 343 was allegedly studied in great detail by the Soviets and played a crucial role in the development of the Ilyushin Il-22, the first Soviet jet-bomber.
