Bolesław Mołojec (Polish pronunciation: [bɔˈlɛswaf mɔˈwɔjɛt͡s]; 9 February 1909, Henryków, Tomaszów Mazowiecki County – 29 or 31 December 1942, Warsaw), known under noms de guerre "Edward" and "Długi", was a Polish communist activist and commander of International Brigades during the Spanish Civil War. He served in the leadership of the Communist Party of Poland's (KPP) youth organization in 1935-1936; disciplined by the Soviet leadership in 1936, a fact that later counted in his favour after Stalinist authorities had purged KPP. Mołojec put himself in charge of the PPR after the 1941 German invasion of the Soviet Union. He was assassinated by his own peers.
