The Copenhagen S-train (Danish: S-tog), is the S-train of Copenhagen, Denmark. It is a hybrid urban-suburban rail serving the Greater Copenhagen region, with the notable exception of Amager. The average distance between stations is 2.0 km, shorter in the city core and inner boroughs, longer at the end of lines that serves suburbs. Of the 85 stations, 32 are located within the central ticket fare zones, 1 and 2. The S-tog is analogous to S-Bahn systems in Germany, and is a separate system from the Copenhagen Metro, which operates in the city centre, Frederiksberg, and Amager.

On weekdays all stations are served at least every 10 minutes until the evening. There are six main lines and one peak hour support line. Since all lines, with exception of one, use the same path through the city core, train departures occur every second minute there, at the general limit of metro lines. On most suburban lines, trains depart every five minutes. On Sundays these time intervals are doubled.

The first line was opened in 1934, which was Klampenborg-Copenhagen H-Vanløse-Frederiksberg, with more lines soon after. Most were converted from steam operated railways to electric, metro-like operation and stations. Today the network forms the heart of public transport in the city, serving more than 357,000 passengers a day. (Together with the Metro they serve more than 500,000.) The S-train is owned and run by DSB S-tog A/S. Similar to the S-Bahns of Berlin, Vienna and Hamburg, the S-train network covers the entire greater urban area. The system is complemented by the Copenhagen Metro, regional trains, local diesel-powered trains within Metropolitan Copenhagen, an extensive bus network and two lines of shuttle boats called "harbour buses". The different networks use a common system for fare zones and tickets.
