Katajanokka Terminal is a ferry terminal located in Katajanokka, in the Southern Harbor of Helsinki, Finland. The shipping company Viking Line operates scheduled services from the terminal to Stockholm and Tallinn. The terminal building was originally a customs warehouse, the harbour building K8. It was built in 1937 designed by the city architect Gunnar Taucher. The building was changed to a passenger terminal in 1977, when the Finnjet started traffic between Helsinki and Travemünde, Germany.
