Onikişubat is a planned district and second level municipality in Kahramanmaraş Province, Turkey. According to Law act no 6360 all Turkish provinces with a population of more than 750,000 will be metropolitan municipality, and the districts within the metropolitan municipalities will be second-level municipalities. The law also creates new districts within the provinces in addition to present districts. These changes will be effective by the local elections in 2014.
Thus after 2014 the present Kahramanmaraş central district will be split into two. A part will be named Onikişubat and the name Kahramanmaraş will be reserved for the metropolitan municipality. ("Onikişubat" or 12 February refers to the date of recovery of Kahramanmaraş during the Turkish War of Independence in 1920.)
