Mohammad Reyshahri (Persian: محمد محمدی ری‌‌شهری), also known as Mohammad Mohammadi-Nik (29 October 1946 – 21 March 2022), was an Iranian politician, cleric, judge and religious scholar, who notably served as Chief Judge of the Revolutionary Military Tribunal (1979–1984), as the first Minister of Intelligence and Security (1984–1989) in the cabinet of Prime Minister Mir-Hossein Mousavi and as Prosecutor-General of Iran from 1989 to 1991.

[4] Reyshahri began to involve himself in political activities in June 1963 during the religious revolts after Khomeini's famous speech in Qom.

[2] After the victory of the revolution, Reyshahri served as Chief Judge of the Revolutionary Military Tribunal from 1979 to 1984, and was involved in investigating and purging the plotters of the Nojeh coup (which was planned for 8 July 1980 by supporters of Shapour Bakhtiar and was reported to Reyshahri by Saeed Hajjarian) as well as the Ghotbzadeh coup, which led to the execution of Sadegh Ghotbzadeh and the removal of grand ayatollah Ayatollah Kazem Shariatmadari from being a marja by the Society of Teachers of the Qom Hawza.

This independent entity was thereafter separate from the office responsible for endowments and charity, with Iranian law stating that "all of the Hajj's cultural, political, and outreach issues are under the exclusive authority of the Supreme Leader's Representative".

Reyshahri wrote more than 75 books on Islamic teachings,[9] and one of them, entitled The Wisdom of Christ, was translated and published in English in South Africa to mark the New Year in 2022.
