The Swedish invasion of Ösel (Svenska invasionen av Ösel, Svenske invasion af Øsel) was a Swedish invasion of the then-Danish island of Øsel (Saaremaa) lasting from 1611 to 1612 during the Kalmar War. The Swedish forces managed to take most of the island, save Arensborg (Kuressaare) which, despite being low on men and supplies, held out to the war's end.
