Harold Edgar Clurman (September 18, 1901 – September 9, 1980) was an American theatre director and drama critic, "one of the most influential in the United States". He was most notable as one of the three founders of the New York City's Group Theatre (1931–1941). He directed more than 40 plays in his career and, during the 1950s, was nominated for a Tony Award as director for several productions. In addition to his directing career, he was drama critic for The New Republic (1948–52) and The Nation (1953–1980), helping shape American theater by writing about it. Clurman wrote seven books about the theatre, including his memoir The Fervent Years: The Group Theatre And The Thirties (1961).
