Miron Constantinescu (13 December 1917 – 18 July 1974) was a Romanian communist politician, a leading member of the Romanian Communist Party (PCR, known as PMR for a period of his lifetime), as well as a Marxist sociologist, historian, academic, and journalist.
Initially close to Communist Romania's leader Gheorghe Gheorghiu-Dej, he became increasingly critical of the latter's Stalinist policies during the 1950s, and was sidelined together with Iosif Chi?inevschi.
Reinstated under Nicolae Ceausescu, he became a member of the Romanian Academy.
