The Second Battle of Breitenfeld, also known as the First Battle of Leipzig, took place during the Thirty Years' War on 2 November 1642 at Breitenfeld, north-east of Leipzig in Germany. A Swedish Army commanded by Lennart Torstensson defeated an Imperial Army under Archduke Leopold Wilhelm of Austria and his deputy Ottavio Piccolomini.

Victory allowed the Swedes to occupy and establish a secure base in Leipzig, the second most important town in the Electorate of Saxony. Although significantly weakened by the defeat and forced onto the defensive, the Imperial Army prevented them from fully exploiting their victory and kept John George I, Elector of Saxony from making peace with Sweden.
