The Torstenson War^[a] was fought between Sweden and Denmark–Norway from 1643 to 1645. The name derives from Swedish general Lennart Torstenson.

Denmark-Norway had withdrawn from the Thirty Years' War in the 1629 Treaty of Lübeck. After its victories in the war, Sweden felt it had to attack Denmark-Norway due to its advantageous geographical position in relation to Sweden. Sweden invaded in a short two-year war. In the Second Treaty of Brömsebro (1645), which concluded the war, Denmark-Norway had to make huge territorial concessions and exempt Sweden from the Sound Dues, de facto acknowledging the end of the Danish-Norwegian dominium maris baltici. Danish-Norwegian efforts to reverse this result in the Second Northern, Scanian and Great Northern wars failed.
