Mojsije Petrović (Belgrade, Ottoman Empire, 1677 - Belgrade, Habsburg Monarchy, 27 July 1730) was the first Metropolitan of the unified Metropolitanate of Belgrade and Karlovci and, as such, exercised great influence among the Serbian and Romanian Orthodox faithful in the Habsburg Monarchy.His close friendships with Prince Eugene of Savoy and Count Claude Florimond de Mercy contributed substantially to Charles VI's victories at the Battle of Petrovaradin in August 1716, Belgrade (1717), and the conquest of the Banat of Temesvár over the Ottoman Turks.
