The Jāmeh Mosque of Semnan (Persian: مسجد جامع سمنان, romanized: Masjid-e Jameh-e Semnan; Arabic: جامع سمنان) is a Shi'ite Friday mosque (jāmeh), located in the city of Semnan, in the province of Semnan, Iran. It is believed that this mosque was built in the 5th century AH (11th century CE) on the ruins of a fire temple. Subsequently, there have been many changes and developments to the mosque structure, with traces of the Seljuq and Timurid eras most notable.
Both the Seljuk style mosque and its minaret were added to the Iran National Heritage List on 6 January 1932, administered by the Cultural Heritage, Handicrafts and Tourism Organization of Iran.
