Vanhakaupunki (Finnish: [ˈʋɑnhɑˌkɑu̯puŋki]; Swedish: Gammelstaden) is a neighbourhood of the city of Helsinki, Finland, to the north of Toukola.

The Swedish king Gustav Vasa founded Helsinki on June 12, 1550 on the mouth of the Vantaa River on the site of the medieval village of Forsby (Finnish: Koskela).

The city was to compete with Tallinn for the commerce in the Bay of Finland and to reduce the illegal trading done by peasants.

In the 1640s, Helsinki was moved to its current location on the Vironniemi peninsula because of better harbour conditions, to boost the city commerce.

The only building drawn on the map is the church, which was located west of the north end of the current Vanhankaupungintie road.
