Abdullah II bin al-Hussein (Arabic: الملك عبد الله الثاني بن الحسين‎, al-Malik ʿAbdullāh aṯ-ṯānī bin al-Ḥusayn born Amman, 30 January 1962) is the current King of the Hashemite Kingdom of Jordan. He ascended the throne on 7 February 1999 after the death of his father King Hussein. King Abdullah is a member of the Hashemite family and is reportedly a 43rd-generation direct descendant of Muhammad. Abdullah has been married to Queen Rania of Jordan since 1993 and his mother is Princess Muna al-Hussein.

Abdullah was born on 30 January 1962 to King Hussein of Jordan and his second wife, the British-born Princess Muna al-Hussein. He was the king's eldest son and as such he was automatically heir apparent to the throne of Jordan under 1952 constitution. However, due to unstable times in the 1960s, King Hussein decided to appoint his brother, Prince Hassan bin Talal, as his heir.

In the 1980s, the King considered arranging the throne to pass to his brother and then to his son Ali, but changed his mind by 1992. He seriously considered appointing one of his nephews as heir, but on his deathbed, on 25 January 1999, he appointed Abdullah as his heir.
