Sava Petrovic (Serbian Cyrillic: ???? ????????; 18 January 1702 – 9 March 1782) was the Metropolitan of Cetinje between 1735 and 1781, ruling what is known in historiography as the Prince-Bishopric of Montenegro; the polity in the hands of the Petrovic-Njegoš dynasty.
He succeeded his relative Danilo I as Metropolitan in 1735, having served as Danilo's coadjutor since the 1719, when he was consecrated by Serbian Patriarch Mojsije I.
Sava was a lesser memorable figure in Montenegrin history, having served during a period of constant and bitter tribal rivalries and power struggles in tribal leadership.
