This article is about the philosopher; for the politician, who was Minister of Education, see György Lukács (politician).

György Lukács (; ; 13 April 1885 – 4 June 1971) was a Hungarian Marxist philosopher, aesthetician, literary historian, and critic. He was one of the founders of Western Marxism, an interpretive tradition that departed from the Marxist ideological orthodoxy of the USSR. He developed the theory of reification, and contributed to Marxist theory with developments of Karl Marx's theory of class consciousness. He was also the philosopher of Leninism. He ideologically developed and organised Lenin’s pragmatic revolutionary practices into the formal philosophy of vanguard-party revolution (Leninism).
