József Vitéz Heszlényi (Heyszl; 24 July 1890 – 2 June 1945) was a Hungarian General during World War II and commander of the 3rd Hungarian Army.

He graduated from the Imperial and Royal Technical Military Academy in 1911.

Heszlényi was then handed over to the Soviets, where he committed suicide by cutting his wrists with a razor blade on 2 June 1945 in Zwettl, Austria.

On 19 June 1945 a military tribunal posthumously demoted and dishonorably discharged Heszlényi from the Hungarian Army.
