Ballerup station is a suburban rail railway station serving the suburb of Ballerup northwest of Copenhagen, Denmark. It is situated in the middle of the suburb, and the station complex includes a shopping center and a large bus terminal, which is the terminus for many local bus lines and buses through the rural areas outside the urban corridor that continues towards Frederikssund.
The station is located on the Frederikssund radial of Copenhagen's S-train network. It is the terminus for most trains on the C S-train service, and contains a group of parking and reversing tracks between the main tracks west of the platform.
Ballerup was one of the original stations on the railway to Frederikssund, which opened on 17 June 1879. On 15 May 1949, the S-train network was extended to Ballerup and, for 40 years, Ballerup was a main transfer point between S-trains and the local diesel trains between Ballerup and Frederikssund. On 28 May 1989, S-train service was extended all the way to Frederikssund.
