大阿亚图拉侯赛因-阿里·蒙塔泽里（阿拉伯语：حسینعلی منتظری‎，拉丁化：Grand Ayatollah Hussein-Ali Montazeri，1922年－2009年12月19日）是伊朗重要伊斯兰教神学家、民主倡导者、作家及人权活动家。他曾参与领导1979年伊朗伊斯兰革命，后指定为最高领袖大阿亚图拉霍梅尼的继任者。1989年，蒙塔泽里因批评政府政策干涉人民自由，侵犯人民权利而与霍梅尼交恶。蒙塔泽里晚年在库姆度过，尤其对改革派运动仍具有极大的政治号召力。他通常被认为是伊朗最博学的伊斯兰教学者，也是伊斯兰教什叶派的大阿亚图拉（宗教权威）。

Hussein-Ali Montazeri (1922 – 19 December 2009; Persian:حسینعلی منتظری‎‎‎) was a prominent Iranian scholar, Islamic theologian, Shia Islamic democracy advocate, writer and human rights activist. He was one of the leaders of the Iranian Revolution in 1979. He was once the designated successor to the revolution's Supreme Leader Ayatollah Khomeini, with whom he had a falling-out in **** over government policies that Montazeri claimed infringed on people's freedom and denied them their rights. Montazeri spent his later years in Qom, and remained politically influential in Iran, especially to the reformist movement. He was widely known as the most knowledgeable senior Islamic scholar in Iran and a Grand Marja (religious authority) of Shia Islam.
