The king of the Hashemite Kingdom of Jordan (Arabic: ملك المملكة الأردنية الهاشمية) is the monarchical head of state of Jordan. He serves as the head of the Jordanian monarchy—the Hashemite dynasty. The king is addressed as His Majesty (صاحب الجلالة).
Jordan is a constitutional monarchy. However, the king is vested with somewhat more executive and legislative power than is typically the case for constitutional monarchs. He is commander-in-chief of the Jordanian Armed Forces, appoints the prime minister and the directors of security agencies. He also appoints the members of the upper house of Parliament, the Senate, as well as the members of the Constitutional Court.
