Rade Koncar (Serbian Cyrillic: ???? ??????; 6 August/28 October 1911 – 22 May 1942) was a Croatian Serb politician and leader of the Yugoslav Partisans in the Independent State of Croatia and Dalmatia during the early stages of World War II in Yugoslavia.
He became a member of the Communist Party of Yugoslavia (KPJ) in 1934 and was arrested in 1936 when the Belgrade branch of the party was banned by Yugoslav authorities.
After serving one year of hard labour in Sremska Mitrovica prison he was released and elected political secretary of the central committee of the Communist Party of Croatia (KPH) in Zagreb.
In October 1940, he was made a member of the central committee of the KPJ at the Fifth National Conference of the Communist Party of Yugoslavia.
Following the April 1941 Axis occupation of Yugoslavia Koncar took part in the anti-fascist uprising which retook areas from German control in Serbia, and personally led attacks against Axis forces in Independent State of Croatia.
Having relocated to Governorate of Dalmatia in October 1941, in November 1941 he was ambushed by fascist agents, arrested and beaten.
The Ustaše disclosed his identity to Italian authorities who then put him on trial.
Koncar was sentenced to death and executed alongside twenty-five others on 22 May 1942 in Šibenik.
He was posthumously named the first People's Hero of Yugoslavia and was revered as a war hero.
