The Güzelyalı railway station (Turkish: Güzelyalı istasyonu) is a railway station in Pendik, Istanbul, on the Marmaray line. It was a stop on the Haydarpaşa suburban commuter rail line until 2012. The original station had two side platforms with two tracks.
The station was closed on 1 February 2012, when all train traffic between Pendik and Arifiye was temporarily suspended due to construction of the Ankara-Istanbul high-speed railway. It was demolished shortly thereafter and a new station built in its place, consisting of an island platform serving two tracks, with a third express track on the south side.
Güzelyalı Station opened in 12 March 2019 along with the entire Marmaray line.
