The Truce of Mitawa or Truce of Mitau, signed in November 1622 in Jelgava (Mitawa, Mitau), ended the Polish–Swedish War (1620–1622).
The Commonwealth was forced to cede the Duchy of Livonia north of the Daugava River to Sweden, and retained only a nominal control over the south-eastern territories near Riga as well as the Duchy of Courland. The truce lasted till March 1625, when a new war wave of hostilities erupted in Lithuania. It was soon followed by the Polish–Swedish War (1625–1629).
