Korsør railway station (Danish: Korsør Station or previously Korsør Banegård) is a railway station serving the town of Korsør in southwestern Zealand, Denmark. It is located in the northern part of the town, about 3 km (1.9 mi) north of the historic town centre.

Korsør station is located on the main line Copenhagen–Fredericia railway from Copenhagen to Funen and Jutland. The station opened in 1856 as the western terminus of the Vestbanen railway line from Copenhagen to Korsør. The original station was located by the harbour from where there was connection via railway ferry across the Great Belt to Nyborg on the island of Funen. Korsør station was moved to its current location in 1997 with the opening of the railway section of the Great Belt Bridge.

The station offers direct InterCity services to Copenhagen, Funen and Jutland, regional rail services to Copenhagen and Odense operated by the national railway company DSB.

Korsør station's second and still-existing station building was built in 1907 to designs by the Danish architect Heinrich Wenck (1851–1936), known for the numerous railway stations he designed across Denmark in his capacity of head architect of the Danish State Railways. The station building was listed in the Danish registry of protected buildings and places in 1992.
