Kemal Kılıçdaroğlu (pronounced [ceˈmal kɯɫɯtʃˈdaɾoːɫu]; born 17 December 1948) is a Turkish social democrat politician. He is currently leader of the Republican People's Party (CHP) and Leader of the Main Opposition in Turkey. He has been a Member of Parliament for İstanbul since 2002.

He was nominated by the CHP as candidate for Mayor of Istanbul in the 2009 local elections, in which he gained 36.8% of all votes. He is considered likely to breathe new life into the CHP.

He was born on December 17, 1948 in Ballıca village of Nazimiye district in Tunceli Province, eastern Turkey to Kamer, a clerk-recorder of deeds and his wife Yemuş. He was the fourth of seven children. His father was among thousands of exiled Alevis following the failed Dersim Rebellion.

The family belonged to the Cebeligiller clan of the Kureyşan tribe. There are some claims about his ethnicity; some sources mention that he has Kurdish, Zaza origin, but he said his roots have come from Turkmen. His father changed their family name in the 1950s from originally Karabulut to Kılıçdaroğlu since all the people in the village they lived in had the same family name.
