Marwan Hadid (1934–1976) (Arabic: مروان حديد) was an influential militant leader of the Muslim Brotherhood movement in Syria.
Hadid led a "radical current" of the Brotherhood, and his "endeavors throughout the late 1960s and early 1970s led to the growth of a nationwide network of radical militants who wanted to push the Brotherhood into an open confrontation with the [Baath] regime."
He was captured and died in prison in 1976.
Historian Eugene Rogan characterized Hadid as "one of Hama's most charismatic imams (mosque prayer leaders) in the 1960s and said that he "was particularly successful in recruiting students to the Islamic underground movement." "For many of the young Islamists, Hadid was an inspiration and a role model for Islamic activism."
