The Russo-Turkish War of 1735–1739 between Russia and the Ottoman Empire was caused by the Ottoman Empire's war with Persia and continuing raids by the Crimean Tatars. The war also represented Russia's continuing struggle for access to the Black Sea. In 1737, Austria joined the war on Russia's side, known in historiography as the Austro-Turkish War of 1737–1739.

By the outbreak of the Russo-Turkish war, Russia had managed to secure a favorable international situation by signing treaties with the Persian Empire in 1732–1735 (which was at war with Turkey in 1730–1736) and supporting the accession to the Polish throne of Augustus III in 1735 instead of the French protégé Stanislaw I Leszczynski, nominated by pro-Turkish France. Austria had been Russia's ally since 1726.

The casus belli were the raids of the Crimean Tatars on Cossack Hetmanate (Ukraine) in the end of 1735 and the Crimean khan's military campaign in the Caucasus. In 1736, the Russian commanders envisioned the seizure of Azov and the Crimea.
