The Polatlı–İzmir high-speed railway is a 588 km (365.37 mi) long high-speed railway currently under construction in Turkey. Once completed, it will be the longest high-speed railway in the country, surpassing the Istanbul-Ankara HSR which holds the title since 2014.

The railway will split from the Polatlı-Konya high-speed railway about 27 km (17 mi) south of Polatlı junction, where the Polatlı-Konya HSR splits from the Istanbul-Ankara HSR, and head west to Afyonkarahisar, then it will parallel the İzmir–Afyon railway to Menemen, where it will join the railway just north of İzmir, to eventually terminate at Alsancak railway station. Travel times between Ankara-Afyon and Ankara–İzmir are expected to be 1h 30min and 3h 30min, respectively.

Construction of the initial section began in 2012, but was suspended in 2018 when almost 50% of the works had been completed on some sections. The construction was restarted in 2022,^[2] and planned to be completed in 2027.^[3]
