The Wazir Khan Mosque (Punjabi and Urdu: مسجد وزیر خان ‎; Masjid Wazīr Khān) is 17th century mosque located in the city of Lahore, capital of the Pakistani province of Punjab. The mosque was commissioned during the reign of the Mughal Emperor Shah Jahan as part of an ensemble of buildings that also included the nearby Shahi Hammam baths. Construction of Wazir Khan Mosque began in 1634 C.E., and was completed in 1641. It is on the UNSCO World Heritage Tentative List.

Considered to be the most ornately decorated Mughal-era mosque, Wazir Khan Mosque is renowned for its intricate faience tile work known as kashi-kari, as well as its interior surfaces that are almost entirely embellished with elaborate Mughal-era frescoes. The mosque has been under extensive restoration since 2009 under the direction of the Aga Khan Trust for Culture and the Government of Punjab, with contributions from the governments of Germany, Norway, and the United States.
