Kazem Seddiqi (Persian: کاظم صدیقی, born 4 March 1951, sometimes with the honorific Ayatollah, and surname anglicised as Sedighi) is an Iranian Shia scholar and Mujtahid currently serving as Tehran's Friday Prayer Temporary Imam.

A rival of President Ahmadinejad, Seddiqi was appointed as interim Friday prayers leader for Tehran by Ayatollah Khamenei in 1 August 2009.

The New York Times characterized the appointment as part of an effort to "reinforce [Khamenei's] authority by cultivating divisions between factions" following the controversial June presidential election.

[1] Lately it has come to light that Ayatollah Kazem Sedighi and his sons have unlawfully took over a 4,200-square-meter (45,200 sq feet) garden at a prime location in northern Tehran through a family company, worth $20 million.

Among the targets of criticism in Seddiqi's khutbahs have been "certain regional countries for `supporting` the leader of the Jundallah terrorist group, Abdolmalek Rigi",[2] the United States President Barack Obama for showing his "ugly face" by preparing a new slate of sanctions against Iran,[3] and women who wear immodest clothing and behave promiscuously, which Seddiqi claims causes earthquakes to occur.
