The Khalidiya Khanqah Mosque and Tekke (), also known as the Mzgawti Xanaqa (), is a religious complex comprising a Sufi mosque, tekke, library, and marketplace, located near the UNESCO World Heritage citadel in the city of Erbil, in the Erbil Governorate of the Kurdistan Region of Iraq. Completed in 1805 CE, the site was renovated in 1961.
The mosque and its adjoining Sufi lodge were founded in 1805 by the Kurdish Muslim scholar, Mullah Hidayatullah al-Arbili, on the orders of a Naqshbandi dervish named Mawlana Khalid al-Naqshbandi. The local Naqshbandi dervishes of Erbil served as the management for the religious complex, amongst them Sheikh Muhammad Salih who supervised a complete rebuild and renovation in 1961. A marketplace was developed around the mosque, as well as the Shar Park opposite it. The surrounding citadel was added to the UNESCO World Heritage List in 2014.
The surrounding neighbourhood of the mosque, dating back to at least 800 years during the reign of the Ayyubids over Kurdistan, has become known as the Khanqah neighbourhood due to its famed presence.
The religious complex is in area, built with bricks, and has capacity for approximately 500 worshippers. The mosque minaret is high with two accessible balconies, while the prayer hall is topped by a large dome with an internal frame structure made out of iron. The library contains ancient manuscripts, religious books, and other material in Arabic, Turkish, and Persian languages. Aside from the prayer hall, there are residential quarters for the Imam, the muezzin, and the mosque's workers.
