Line 3 of the Saint Petersburg Metro, also known as Nevsko-Vasileostrovskaya Line (Russian: Не́вско-Василеостро́вская ли́ния) or Green Line, is a rapid transit line in Saint Petersburg, Russia, which connects city centre with the western and southeastern districts. It was opened in 1967. Since 1994, it has been officially designated as Line 3. It stands out among Saint Petersburg metro lines for two reasons — its stations are almost exclusively of "Horizontal Lift" type and it has the longest inter-station tunnels in the entire system. Metro officials originally intended to add stations in-between the existing ones, but those plans were later abandoned.

The line cuts Saint Petersburg centre on an east–west axis and then turns southeast following the left bank of the Neva River. It is generally coloured green on Metro maps.

Future transfer to Line 5 is planned via Admiralteyskaya.

The Nevskoe depot (№ 5) serves the line. Previously six carriage Em, Ema, and Emx trains were assigned to the line until 2015 while 81-717/714 and 81-540/541 trains operated until 2018. Line 3 currently uses 81-556/557/558, 81-722/723/724, 81-556.1/557.1/558.1, 81-722.3/723.3/724.3 and 81-556.2/557.2/558.2 trains.

Admiralteyskaya was opened in 2011 between Gostiny Dvor and Vasileostrovskaya and became a transfer to Line 5. Proletarskaya was closed for reconstruction on August 25, 2005. Originally, it was intended to reopen on February 25, 2007, but the reconstruction was finished ahead of schedule, allowing the station to reopen on November 17, 2006.

The extension of the line north to Novokrestovskaya and Begovaya was opened in 2018.^[1][2]
