Line M5, officially referred to as the M5 Üsküdar–Sultanbeyli line (), is a rapid transit line of the Istanbul Metro system. It is colored deep purple on the maps and route signs. The M5 is the second rapid transit line on the Asian side of Istanbul, the other in service since August 2012, the M4. Furthermore, it is the first driverless rapid transit line in Turkey.

History The contract for the construction of the line's first phase was awarded in October 2011 to the Doğuş Construction Group. Construction of the line in the west–east direction with 16 stations between Üsküdar and Çekmeköy, and its connection line to the depot with a length of , began on 20 March 2012. Projected to cost about 564 million, the line was expected to open in May 2015; however, the expected opening day was then revised to 20 September 2016, until it became clear that it would not open then. In June 2014, 21 six-car driverless trainsets, manufactured by a consortium of CAF and Mitsubishi, were ordered to operate on the line, the first of which was delivered on 21 November 2016. According to news in Turkish TV in November 2016, half of the M5 line (Üsküdar - Ümraniye) would open in January 2017, with driverless trains, and then in early 2017 the new opening date was stated to be 22 March providing there are no further delays. But in April 2017 the opening date had been postponed further to 30 August 2017. Later it was postponed further, first to 14 September 2017 and then to 29 October 2017. The first stage of the line, running from Üsküdar to Yamanevler, finally opened on 15 December 2017. The second stage, from Yamanevler to Çekmeköy, opened on 21 October 2018. The third stage of the line, and the first phase of the extension to Sultanbeyli, opened on 16 March 2024 from Çekmeköy to Samandıra Merkez (excluding Sancaktepe Şehir Hastanesi station). The fourth and final stage of the line, from Samandıra Merkez to Sultanbeyli, including Sancaktepe Şehir Hastanesi station, opened on 22 May 2026.

Earlier plans to extend the line to Sabiha Gökçen International Airport in the future have been cancelled, with the M4 extension now open to this airport.
