The Treaty of Karlowitz was signed in 1699 in Sremski Karlovci (Serbian Cyrillic: Сремски Карловци, German: Karlowitz, Turkish: Karlofça, Hungarian: Karlóca), a town in modern-day Serbia, concluding the Austro-Ottoman War of 1683–1697 in which the Ottoman side was defeated.

Following a two-month congress between the Ottoman Empire on one side and the Holy League, a coalition of various European powers including the Habsburg Monarchy, Polish-Lithuanian Commonwealth, Republic of Venice and the Russian Empire, a treaty was signed on January 26, 1699. The Ottomans ceded most of Hungary, Transylvania and Slavonia to Austria while Podolia passed to Poland. Most of Dalmatia passed to Venice, along with the Morea (the Peloponnesus peninsula), which the Ottomans regained in the Treaty of Passarowitz of 1718.

The Treaty of Karlowitz marked the beginning of the Ottoman decline in Eastern Europe and made the Habsburg Monarchy the dominant power in southeastern Europe.
