Mansoor Hekmat (منصور حکمت; original name Zhoobin Razani; June 4, 1951 - July 4, 2002) was an Iranian Marxist theorist and leader of the worker-communist movement. He opposed the Shah and, after the Islamic Revolution of 1979, led the Worker-Communist Party of Iran (WPI), which is opposed to the Islamic Republic of Iran. He was the husband of fellow politician Azar Majedi.
Born in Tehran, and moved to Shiraz where he graduated in economics, at the University of Shiraz. He moved to London in 1973, where he was introduced to Marxist ideas and became a critic of what he saw as distorted versions of communism, including Russian communism, Chinese communism, the guerrilla warfare movement, social democracy and Trotskyism.
He founded the Union of Communist Militants in 1978, then took part in the Iranian Revolution of 1979–marked by the creation of workers' councils (shoras) — and, unlike the major part of the Iranian left-wing, refused to pay allegiance to Islamism and Supreme Leader Ruhollah Khomeini. He denounced the "myth of a progressive national bourgeoisie".
