The Leningradsky suburban railway line (Russian: Ленинградское направление Октябрьской железной дороги) is one of eleven railway lines used for suburban railway connections between Moscow, Russia, and surrounding areas in Moscow Oblast and Tver Oblast.

The Leningradsky suburban railway line connects Moscow with the station in the northwest, in particular, with the towns of Khimki, Zelenograd, Solnechnogorsk, Klin, Konakovo, and Tver.

The stations the direction serves are located in Moscow, in the towns of Khimki, Solnechnogorsk, and Klin in Moscow Oblast, and in Konakovsky and Kalininsky Districts and the city of Tver of Tver Oblast.

In the northwestern direction, the suburban trains terminate at Kryukovo, Podsolnechnaya, Klin, Konakovo GRES, and Tver.

In 2018, the line was demolished, since it was crossed by the M11 highway, and no bridge or tunnel was included to the construction project.
