Moldauhafen ( Vltava port) is a lot in the port of Hamburg, Germany, that Czechoslovakia acquired on a 99-year lease in 1929 pursuant to the Treaty of Versailles. In 1993, the Czech Republic succeeded to the rights of Czechoslovakia,. The lease will expire in 2028.
The lot is not an exclave as it is not sovereign Czech territory. Previously, a similar arrangement existed for the port of Stettin, now Szczecin, Poland.
The lot is one of three lots that the Czech Republic has rights over. The other two are Saalehafen and Peutehafen. Saalehafen comes under the Versailles Treaty but then-Czechoslovakia purchased Peutehafen in 1929. Both Moldauhafen and Saalehafen are part of the Hamburg free port, and sit on the embankment of Dresdner Ufer and Hallesches Ufer. The area comprises about . The leased premises constitute a duty-free zone that were called the Czecho-Slovak rental zone for inland navigation in the free port of Hamburg.
Peutehafen comprises an area of about . It lies on the narrow peninsula between the Peutekanal and the Peutehafen dock, and is just outside the Hamburg free port.
