The Treaty of Passarowitz is the peace treaty signed in Požarevac, Serbia (German Passarowitz, Turkish Pasarofça, Hungarian Pozsarevác) on July 21, 1718 between the Ottoman Empire on one side and the Habsburg Austria and Venice on the other.

In the years 1714-1718, the Turks had been successful against Venice in Greece and Crete, but had been defeated at Petrovaradin (1716) by the Austrian troops of by Prince Eugene of Savoy.

The treaty reflected the military situation. Turkey lost the Banat of Temesvar, northern Serbia (including Belgrade), northern Bosnia and Lesser Walachia (Oltenia) to Austria. Venice lost its possessions on the Peloponnesus peninsula and on Crete, gained by the Treaty of Carlowitz, retaining only the Ionian Islands and Dalmatia. Belgrade and Lesser Walachia were regained by Turkey in 1739 by the Treaty of Belgrade.
