Østerport station is a metro, S-train and main line railway station in Copenhagen, Denmark. It is located between the districts of Indre By and Østerbro, and is named for the historic Østerport city gate, near the original location of which it is located.

The station is served by some InterCity services across Denmark, regular and frequent regional train services to and from Zealand and southern Sweden, as well as commuter rail services on the S-train network. As of 29 September 2019, Østerport is also served by the Copenhagen Metro City Circle Line and M4.

The station is used by approximately 30,000 passengers each day.

The station opened in 1897 as the southern terminus of the Coast Line from Copenhagen to Helsingør. It was originally named the East Station (Østbanegaarden).

It was originally the terminus for the Coast Line, but when the station was connected with Nørreport Station and Copenhagen Central Station via the Boulevard Line in 1917, the terminus moved to the Central Station. In 1934, the station started serving S-trains.

The station was designed by Danish architect Heinrich Wenck, who was head architect of the Danish State Railways from 1894 to 1921. The station is designed in National Romantic style, a Nordic architectural style that was part of the National Romantic movement during the late 19th and early 20th centuries, and which is often considered to be a form of Art Nouveau.

Although originally intended as a temporary solution, the original station building has survived to the present day. It was restored in the 1980s and again in the 2010s.

The station is served by some InterCity services across Denmark, regular and frequent regional train services to and from Zealand and southern Sweden, as well as commuter rail services on the S-train network. By 2019, the service was included the Copenhagen Metro as well (future line M4).

The metro station is located under the street Østbanegade with the staircase towards Østerport station. Another line M4 later supplement line M3, going to Nordhavn and Ny Ellebjerg.
