Swedish Pomerania was a dominion under the Swedish Crown from 1630 to 1815 on what is now the Baltic coast of Germany and Poland. Following the Polish War and the Thirty Years' War, Sweden held extensive control over the lands on the southern Baltic coast, including Pomerania and parts of Livonia and Prussia.

The Dominions of Sweden or Svenska besittningar were territories that historically came under control of the Swedish Crown, but never became fully integrated with Sweden. This generally meant that they were ruled by Governors-General under the Swedish monarch, but within certain limits retained their own established political systems, essentially their diets. Finland was not a dominion, but a land of Sweden. The dominions had no representation in the Swedish Riksdag as stipulated by the 1634 Instrument of Government paragraph 46: "No one, who is not living inside the separate and old borders of Sweden and Finland, have anything to say at Riksdags and other meetings..."
