The Ryazansky suburban railway line (Russian: Рязанское направление Московской железной дороги) is one of eleven railway lines used for suburban railway connections between Moscow, Russia, and surrounding areas, mostly in Moscow Oblast. The Ryazansky suburban railway line connects Moscow with the stations in the south-east, in particular, with the towns of Lyubertsy, Kurovskoye, and Shatura. The stations the line serves are located in Moscow, in Lyubertsy, Ramenskoye, Voskresensk, Kolomna, and Lukhovitsy in Moscow Oblast, as well as Rybnovsky and Ryazansky Districts and the city of Ryazan in Ryazan Oblast. The suburban trains have their northwestern terminus at Moscow Kazansky railway station in Moscow. In the southeastern direction, the suburban trains terminate at Ippodrom, Faustovo, Vinogradovo, 88km, Shifernaya, Golutvin, Ryazan I, and Ryazan II.^[1] The line is operated by Moscow Railway.

It is electrified and has at least two tracks everywhere between Moscow and Ryazan.^[2] The distance between Kazansky railway station and Ryazan I is 197 kilometres (122 mi).
