Södertälje hamn ("Harbour") (previously Södertälje södra until 1994) is a railway station along Sweden's Western Main Line (Västra stambanan) in Södertälje.

Before Grödingebanan [sv] was constructed in the 1990s, Södertälje hamn was the main train station in Södertälje for national and regional trains. Today it is only used by Stockholm commuter rail.

Passenger traffic

All commuter trains between Stockholm and Södertälje centrum need to charge direction in Södertälje hamn, due to the track layout. To avoid wasting the time needed for the drivers to walk between the driver seats of the 214 metres (702 ft) long trains, extra drivers are used between Södertälje hamn and Södertälje centrum.

There are three commuter rail lines through Södertälje hamn. J40 and J41 go from Södertälje centrum via Stockholm City Station to Uppsala and Märsta respectively. J48 goes from Södertälje centrum to Gnesta.

The station is within walking distance to the Port of Södertälje vicinity as well as the headquarters and main factory of Scania AB.
