The Franco-Swedish War or Pomeranian War was the first involvement by Sweden in the Napoleonic Wars. The country joined the Third Coalition in an effort to defeat France under Napoleon Bonaparte.

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.
