The Government of Punjab (), is the provincial government of the Pakistani province of Punjab. It is based in Lahore, the provincial capital. Its powers and structure are set out in the provisions of the Constitution, in which 41 districts come under its authority and jurisdiction. The government includes the cabinet, selected from members the Punjab Provincial Assembly, and the non-political civil staff within each department. The province is governed by a unicameral legislature with the head of government known as the Chief Minister.
