Nine Countries Sharing the Baltic Sea

The Baltic Sea is bordered by nine sovereign states:

1. Denmark
2. Estonia
3. Finland
4. Germany
5. Latvia
6. Lithuania
7. Poland
8. Russia (Kaliningrad Oblast & Gulf of Finland)

It is a brackish, semi‑enclosed sea with limited exchange through the Danish Straits. The region is linked by the Council of the Baltic Sea States for cooperation on environment, economy, and security.
