The Austro–Turkish War (1663–1664) or fourth Austro–Turkish War is a short war between the Habsburg Monarchy and the Ottoman Empire.

The Ottoman aim is to resume the advance in central Europe, conquer Vienna and subdue Austria.

However, the Habsburg army under Raimondo Montecuccoli succeeds to halt the Ottoman army on its way to Vienna in the Battle of Saint Gotthard and destroy it, while another Austrian army wins another victory at Léva.

Despite these serious Ottoman defeats, the war ends for them with the rather favorable Peace of Vasvár.
