The mausoleum of Ruhollah Khomeini (Persian: آرامگاه روح‌الله خمینی) houses the tombs of Ayatollah Ruhollah Khomeini, his wife Khadijeh Saqafi, and his second son Ahmad Khomeini; and some political figures, such as former President Akbar Hashemi Rafsanjani, former Vice President Hassan Habibi, Lieutenant General Ali Sayad Shirazi, Iranian Revolution figure Sadeq Tabatabaei, and MP Marzieh Hadidchi. The mausoleum is located to the south of Tehran in the Behesht-e Zahra (Paradise of Zahra) cemetery. Construction commenced in 1989 following Khomeini's death on June 3 of that year. It is still under construction, but when completed will be the centerpiece in a complex spread over 20 square kilometres (4,900 acres), housing a cultural and tourist center, a university for Islamic studies, a seminary, a shopping mall, and a 20,000-car parking lot. The Iranian government has reportedly devoted 2 billion US dollars to this development.

The site is a place of pilgrimage for followers of Khomeini. It is used symbolically by government figures, and is on occasion visited by foreign dignitaries. Every year, Khomeini's death anniversary is marked on 4 June at the mausoleum in a ceremony that is attended by governmental officials, foreign ambassadors, and others. Khomeini's grandson Ayatollah Seyyed Hassan Khomeini is in charge of caring for the mausoleum.
