The "Blue Mosque", also known as the "Gök Jami", (Azerbaijani: Göy məscid, Armenian: Կապույտ Մզկիթ, Kapuyt Mzkit or Գյոյ Մզկիթ, Gyoy Mzkit; Persian: مسجد کبود‎, Masjed-e Kabud), is a mosque in Yerevan, Armenia.

The Yerevan region had been under the control of various Muslim rulers since the incursions of Timur in the 14th century. From the second third of the 18th century, after it had been taken from the Ottoman empire, it had been a province of Iran (ruled successively by Nadir Shah, Karim Khan Zand and the dynasty from the Qajar tribe), before it fell to the Russian empire in 1827.

For the mosque's construction, various dates from the mid-18th century are cited in literature. According to a tradition reported by the 19th-century traveller H.F.B. Lynch, it was erected during the period of the Iranian ruler Nadir Shah (1736–47) by the local gouvernor Husayn Ali Khan.George Bournoutian names Husayn Ali Khan as the patron of the building, but places his reign in the years 1762-83. According to Vladimir M. Arutyunyan et al. construction started in 1760 and was completed under Husayn Ali Khan in 1764-68.

Yerevan (Armenian: Երևան, Armenian pronunciation: [jɛɾɛˈvɑn]) is the capital and largest city of Armenia and one of the world's oldest continuously-inhabited cities. Situated along the Hrazdan River, Yerevan is the administrative, cultural, and industrial center of the country. It has been the capital since 1918, the thirteenth in the history of Armenia.

The history of Yerevan dates back to the 8th century BC, with the founding of the fortress of Erebuni in 782 BC by king Argishti I at the western extreme of the Ararat plain. After World War I, Yerevan became the capital of the Democratic Republic of Armenia as thousands of survivors of the Armenian Genocide settled in the area. The city expanded rapidly during the 20th century as Armenia became one of the fifteen republics in the Soviet Union. In fifty years, Yerevan was transformed from a town of a few thousand residents within the Russian Empire, to Armenia's principal cultural, artistic, and industrial center, as well as becoming the seat of national government.
