Office of the Supreme Leader of Iran

The Office of the Supreme Leadership Authority (Persian: دفتر مقام معظم رهبری, Daftar-e Magham-e Moazzam-e Rahbari), also known in shortform as the House of the Leadership (Persian: بیت رهبری, Beit-e Rahbari), was the official residence, bureaucratic office and principal workplace of Ali Khamenei as supreme leader of Iran from 1989 to 2026, when the compound was destroyed as Khamenei was assassinated in a series of airstrikes.

Its structure was a mixture of traditional Beit (religious office of Marja') and bureaucracy. The institution was located in central Tehran and was run by Mohammad Mohammadi Golpayegani. In 2026, it was estimated that 4,000 people were working at its headquarters and another 40,000 affiliated with the office throughout the Iranian government.
