The S2 is a commuter rail route forming part of the Milan suburban railway service (Italian: Servizio ferroviario suburbano di Milano), which converges on the city of Milan, Italy.

The route operates over the infrastructure of the Milan–Asso and Milan Passante railways. Like all but one of the other Milan suburban railway service routes, it is operated by Trenord.

Line S2, a cross-city route, heads initially in a southwesterly direction from Mariano Comense to Seveso, and then south to Milano Bovisa-Politecnico. From there, the line runs across the municipality of Milan, via the Milan Passante railway, to Milano Rogoredo.

The S2 was activated on 12 December 2004, and operated initially between Mariano Comense and Milano Porta Vittoria.

With the change of timetable on 15 June 2008, the line was extended from Milano Porta Vittoria to Milano Rogoredo, where there is interchange with regional trains and long-distance services to and from Genoa, Bologna and Mantua.

The initial plans for the line foresaw a further extension from Milano Rogoredo to Pavia, but that has not materialized: Pavia since been connected to the suburban railway service by the new line S13.

The stations on the S2 are as follows (stations with blue background are in the municipality of Milan):
