Østergade 13 is a Historicist building complex situated on the shopping street Strøget in central Copenhagen, Denmark.

Originally two separate 18th-century buildings, three and four bays wide, respectively, Østergade 13 owes its current appearance to a renovation in 1856.

The western building was constructed prior to the Copenhagen Fire of 1728.

The present building is a fourwinged complex surrounding a central courtyard.

It features a lunette with a silhouette of a grouop of people and the house number just inside the main entrance.
