The Harburg S-Bahn line is a railway line in southern Hamburg, Germany. It starts at Hamburg Hauptbahnhof and runs via Harburg to Stade. It mostly runs parallel with the line to Hanover and the Lower Elbe line and is now part of the Hamburg S-Bahn lines S3 and S31.

The route begins at the Hauptbahnhof, where it climbs a steep ramp before crossing the tracks of the main lines to Berlin and to Lübeck. After running on a concrete viaduct, on which, Hammerbrook station is located, the line crosses the southern freight railway bypass and the Northern Elbe bridge. The line now runs directly parallel with the line to Hanover. After Veddel and Wilhelmsburg stations the line moves away from the Hanover line and dives into a tunnel. The line passes through the stations of Harburg, Harburg Rathaus (which has three platforms) and Heimfeld and then climbs to the surface and runs parallel with the Lower Elbe line. It then passes through the stations of Neuwiedenthal and Neugraben, which has a parking area. After this station there is a change in electrical systems, where S-Bahn trains switch from third rail to overhead wire electrification. The S-Bahn trains then run along the Lower Elbe line, which was upgraded for S-Bahn services in 2006 and 2007.

After the inclusion of Harburg-Wilhelmsburg in Hamburg in 1937, the Harburg–Neugraben line was included in the Hamburg S-Bahn network for ticketing purposes. After the founding of the Hamburg Transport Association in 1967, locomotive-hauled trains provided S-Bahn services on the route, marketed as line S3. The long-distance tracks were used between Hamburg Hauptbahnhof and Hamburg-Harburg station. Although this section of the line had four tracks, one pair of tracks was reserved for freight traffic.
