The 2012–13 Turkish Cup () was the 51st season of the Turkish Cup. Ziraat Bankası is the sponsor of the tournament, thus the sponsored name is Ziraat Turkish Cup. The winners earned a berth in the play-off round of the 2013–14 UEFA Europa League. Fenerbahçe are the defending champions. The winners also qualified for the 2013 Turkish Super Cup.

In a bet to widen the audience and turn the cup into a true national cup, a format change has been made for this season. The number of participating teams increased from 57 to 156, allowing teams from Turkish Regional Amateur League to have a shot at the cup. The knockout qualifying format of the 2011–2012 season have been revised. The group stage matches that were contested between 2005 and 2011 returned as a round-robin tournament.
