List of World Heritage Sites in Iran

The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Iran accepted the convention on 26 February 1975, making its historical sites eligible for inclusion on the list. As of 2019, twenty-four sites in Iran are included.
The first three sites in Iran, Meidan Naghshe Jahan, Isfahan, Persepolis and Tchogha Zanbil, were inscribed on the list at the 3rd Session of the World Heritage Committee, held in Paris, France in 1979. They remained the Islamic Republic's only listed properties until 2003, when Takht-e Soleyman was added to the list. The latest addition was the Hyrcanian forests, inscribed in 2019.
