This is a list of major cities and towns around the Baltic Sea, as well as some notable cities/towns with a small population. The census for Copenhagen, Helsinki and Stockholm includes the urban area.

Usedom (German: Usedom [ˈuːzədɔm] , Polish: Uznam [ˈuznam]) is a Baltic Sea island in Pomerania, divided between Germany and Poland. It is the second largest Pomeranian island after Rügen, and the most populous island in the Baltic Sea.

It lies north of the Szczecin Lagoon estuary of the Oder river. About 80% of the island belongs to the German district of Vorpommern-Greifswald in the state of Mecklenburg-Vorpommern. The eastern part and the largest city on the island, Świnoujście, are part of the Polish West Pomeranian Voivodeship. The island's total area is 445 square kilometres (172 square miles) – 373 square kilometres (144 square miles) in the German part and 72 square kilometres (28 square miles) in the Polish part. Its population is 76,500 (German part 31,500; Polish part 45,000).

The autostrada A6 in Poland is a short motorway that starts at the Polish/German border at Kołbaskowo/Pomellen connecting to the German A11 autobahn. It forms a southern bypass of the Szczecin metropolitan area and terminates at Rzęśnica interchange to the east of the city, from where it continues in an expressway standard as S3 towards Świnoujście and S6 towards Gdańsk.Its length is 29.2 km (18.1 mi). The motorway is part of the European route E28.

Expressway S3 or express road S3 (in Polish droga ekspresowa S3) is a Polish highway, which runs from Świnoujście on the Baltic Sea through Szczecin, Gorzów Wielkopolski, Zielona Góra and Legnica, to the border with the Czech Republic, where it will connect to the planned D11 motorway.

The road was constructed from 2008 until October 2025. Its total length is 470.6 km (292.4 mi), but the last 3 km near the border remain closed to traffic until the connecting stretch of the D11 motorway is constructed in Czech Republic. This stretch is expected to be opened around 2026.

The Świna (German: Swine; Pomeranian: Swina) is a channel in northwest Poland, between 2 and 4 km (1.2 and 2.5 miles) from the German border. It connects the Szczecin Lagoon with the Baltic Sea separating the islands of Uznam (German: Usedom) and Wolin. It is a part of the Oder estuary, and carries about 75% of that river's waterflow (of the remainder, Peenestrom carries 15% and Dziwna 10%). It has a length of about 16 km (9.9 miles). Świnoujście is a major town at the end of the channel towards the Baltic Sea.

The German Empire dammed and deepened the straits from 1874 to 1880 to create the Kaiserfahrt (Piast canal). It connects the northern part of the Świna directly with the Szczecin Lagoon and the Pomeranian harbor of Szczecin. The straits thus gained importance as a direct waterway to the industrial city. The territory along the straits' path was transferred from Germany to Poland following World War II.

The Bay of Pomerania (Polish: Zatoka Pomorska [zaˈtɔ.ka pɔˈmɔr.ska]; German: Pommersche Bucht; Kashubian: Pòmòrskô Hôwinga) is a basin in the southwestern Baltic Sea, off the Pomeranian shores of Poland and Germany. It stretches between the northernmost tip of the island of Rügen called Gellort northwest of Cape Arkona in the west, and the village of Jarosławiec in the east. In the south, it is bounded by the islands of Usedom/Uznam and Wolin, which separate it from the Szczecin Lagoon which is flown through by the Oder River, and is connected to the bay by three straits, the Dziwna, Świna, and Peenestrom.

The Bay of Greifswald with the islands of Koos and Vilm is a large sub-bay in the southwest of the Bay of Pomerania. Apart from Rügen, Usedom/Uznam, and Wolin, the islands Greifswalder Oie and Ruden also lie in the Bay of Pomerania. Maximum depth is 20 metres and salinity is about 8%. The main ports on the Bay of Pomerania are Mukran Port in Sassnitz-Mukran, the port of Świnoujście, the port of Kołobrzeg, the port of Greifswald on the mouth of the Ryck River in Greifswald-Wieck, the port of Dziwnów, and the port of Wolgast.

Wolin (Polish: [ˈvɔlin]; German: Wollin [vɔˈliːn]) is a Polish island in the Baltic Sea, just off the Polish coast. Administratively, the island belongs to the West Pomeranian Voivodeship. Wolin is separated from the island of Usedom (Uznam) by the Strait of Świna, and from mainland Pomerania by the Strait of Dziwna. The island has an area of 265 km (102 sq mi) and its highest point is Mount Grzywacz at 116 m above sea level. The number of inhabitants is 30,000. Eastern suburbs of the city of Świnoujście extend to the Wolin island, while the towns of Międzyzdroje and Wolin lie further east.

Water from the river Oder flows into the Szczecin Lagoon and from there through the Peene west of Usedom, Świna and Dziwna into the Bay of Pomerania in the Baltic Sea.
