Suadiye railway station () is a station on the Marmaray cross-city rail service in the mostly residential neighbourhood of Suadiye in Kadñköy, Istanbul.
The old station was a stop on the Haydarpaà Âa suburban commuter line from 1951 to 2013. It was built in 1910 by the Ottoman Anatolian Railway (CFOA), as the neighbourhood began to expand in the late 1900s and still survives alongside the new replacement station.
The new station opened, belatedly, for service in 2019.
