József Vitéz Heszlényi (Heyszl; 24 July 1890, Igló, county – 2 June 1945) was a Hungarian General during World War II and commander of the 3rd Hungarian Army. On May 8, 1945 Heszlényi, along with his son József Heszlényi Jr., who served on the staff of his father, were captured by American troops. Heszlényi was then sent to a POW camp in the Soviet Union where he cut his wrists with a razor blade on June 2, 1945. On June 19, 1945 a military tribunal posthumously demoted and dishonorably discharged Heszlényi from the Hungarian Army.
