The 18th Republican People's Party Extraordinary Convention (Turkish: 18. CHP Olağanüstü Kurultayı) took place on 5 and 6 September 2014 in order to elect a leader of the Republican People's Party (Cumhuriyet Halk Partisi - CHP), a Turkish centre-left political party. Initially, an ordinary convention was due to be held in 2014, two years after the previous one in 2012. However, the party's incumbent leader Kemal Kılıçdaroğlu accepted calls for an extraordinary convention to be held following the loss of the CHP's presidential candidate Ekmeleddin İhsanoğlu in the presidential election held in August. The ordinary convention will thus be held in 2015 instead.
