Abdullah Gül, GCB, GColIH, Ph.D. (born October 29, 1950) is the 11th President of the Republic of Turkey, serving in that office since 28 August 2007. He previously served for five months as Prime Minister from 2002 to 2003, and as Minister of Foreign Affairs from 2003 to 2007.

Prime Minister Recep Tayyip Erdoğan's nomination of Gül as a presidential candidate drew strong and highly vocal opposition from ardent supporters of secularism in Turkey. In May 2007, Gül's first bid for presidency was blocked by the Constitutional Court, in a climate of secularist concern regarding views Gül had expressed during his Welfare Party years, and the fact that his wife, Hayrünnisa Gül, wears a headscarf, seen by some as a symbol of political Islam. However, following the parliamentary elections in July the same year, which were won by the AKP with 46.6% of the popular vote, he was eventually elected President on August 28, 2007 and was sworn in the same day, becoming the first former-Islamist President in the modern history of Turkey. In September 2008 he became the first Turkish leader to visit neighbouring Armenia, sparking a major debate in Turkey.

President Gül was born in Kayseri, a city in central Anatolia. His father is Ahmed Hamdi Gül, a retired air force mechanic, and his mother is Adviye Gül (née Satoğlu). His family has lived in the Güllük district of Kayseri for about a century. His ancestry/ethnicity according to a Çankaya Presidential Residence statement is "Turkish Muslim." Gül was also called with the name Cumhur(which means 'people') by his family.
