Poland’s seaports are a critical part of the country’s transport and logistics system, linking the Baltic Sea (and the wider global shipping network) with Central Europe by road, rail, and inland waterways. If you’re researching trade, travel, infrastructure, or simply want verified official sources, this guide maps Poland’s key seaports, explains who manages them, and provides the official websites you can trust.
Poland’s seaport system in one glance
Poland officially identifies four seaports of fundamental importance to the national economy: Gdańsk, Gdynia, Szczecin, and Świnoujście.
This status comes from Poland’s legal framework for ports and harbours, which sets rules for management entities, development, and oversight.
Alongside these four, Poland has many other coastal ports and harbours (fishing ports, marinas, regional ports). Importantly, Maritime Offices publish official lists of ports/harbours and their managing entities (useful when you need a verified “who runs this port?” source).
Major Polish seaports (fundamental importance)
Below are the four ports Poland classifies as fundamental to the national economy, plus the official port authority sites.
Port of Gdańsk (Gdańsk)
What it is: The Port of Gdańsk is presented by its authority as the largest Polish seaport, with both outer (deepwater) and inner port areas, handling a wide range of cargo types.
Who manages it: Port of Gdańsk Authority S.A. (Zarząd Morskiego Portu Gdańsk S.A.), which manages port property/infrastructure and development activities.

How to verify an “official port website” in Poland
If you find multiple sites claiming to represent a port (common with tourist pages), use one of these verification methods:
- Check the Ministry of Infrastructure (policy/oversight context)
The Ministry’s official page explains Poland’s major port framework and the four ports of national-economic importance. - Use Maritime Office “official lists” (ports + managing entities)
For example, the Maritime Office in Gdynia publishes an official list of ports/harbours and the managing entities, including a downloadable PDF. - Look for the port’s public-information portal (BIP) or formal company identity
Many port managing entities publish official contact details and corporate identifiers (KRS/REGON/NIP) on their sites or BIP pages (e.g., Kołobrzeg, Ustka).
FAQ: Seaports in Poland
How many “main” seaports does Poland officially recognize at the top level?
Poland’s Ministry of Infrastructure identifies four seaports of fundamental importance: Gdańsk, Gdynia, Szczecin, Świnoujście.
Are Szczecin and Świnoujście managed together?
Yes—an official Seaports Authority (ZMPSiŚ S.A.) is responsible for both ports and describes itself as the managing entity under the ports-and-harbours law framework.
Where can I find an official list of smaller ports and harbours?
Maritime Offices publish lists of ports/harbours and their managing entities (the Maritime Office in Gdynia provides one such official list with a downloadable PDF).
Conclusion
If you want verified, non-invented information about seaports in Poland, start with the official framework: Poland’s Ministry of Infrastructure confirms the four ports of fundamental national-economic importance—Gdańsk, Gdynia, Szczecin, Świnoujście—and each has a dedicated, official port authority website.
For regional ports (Police, Kołobrzeg, Elbląg, Ustka, Darłowo and others), rely on official port-company sites, BIP pages, and Maritime Office lists to confirm who the managing entity is.
