The War of Deposition against Karl Knutsson (Swedish: Avsättningskriget mot Karl Knutsson), also called the crisis of 1457 (Swedish: krisen 1457) and Jöns Bengtsson's Throne Usurpation of 1457 (Swedish: Jöns Bengtssons tronomvälvning år 1457) occurred in the winter of 1457 during the final stages of the Dano-Swedish War of 1449–1457.

It started when Archbishop Jöns Bengtsson (Oxenstierna) and other pro-unionists took advantage of Karl Knutsson's absence in Östergötland, formally rebelling after Jöns Bengtsson renounced his loyalty. During the rebellion, both sides fought a battle at Älgsundet, ending in a crushing rebel victory and forcing Karl Knutsson to retreat back to Stockholm, which capitulated on 24 February after Karl Knutsson escaped to Danzig.
