Line M12, officially referred to as the M12 60. Yıl Parkı-Kazım Karabekir line, is a rapid transit line of the Istanbul Metro system, currently under construction in the Asian part of Istanbul, Turkey.

Built by the Istanbul Metropolitan Municipality, the line will be 13.03 km (8.10 mi) long with 11 stations. The travel time between the end stations will be 21 minutes.[1] It is expected that it will carry around 44,000 riders per hour per direction.[1] The line will run through three districts of Istanbul, namely Kadıköy, Ataşehir and Ümraniye. It will connect to other rapid transit lines at Tütüncü Mehmet Efendi station to the Marmaray commuter rail, at Yenisahra to line M4 Kadıköy–Sabiha Gökçen Airport, and at Çarşı to line M5 Üsküdar–Samandıra Merkez.[2]

The investment budget of the construction is 2.376 billion.[3] The construction of the metro began with work at the southern terminus, 60. Yıl Parkı, in August 2017,[2] however work was stopped on 3 January 2018.[4][5]

The new mayor, Ekrem İmamoğlu, announced that the metropolitan municipality restarted the construction works. The first test runs on the line were launched on March 14, 2024, between Göztepe and Kazım Karabekir,[6] but construction on the line stopped again later in 2024.[5] Work restarted in October 2025, with the line's operation now expected to begin in December 2026.[5]
