The 2012–13 Montenegrin First League was the seventh season of top-tier football in Montenegro. The season began on 11 August 2012 and ended on 1 June 2013. The mid-season winter break began on 2 December 2012 and ended on 7 March 2013. FK Budućnost Podgorica are the defending champions.
Last season, Bokelj, Berane, and Dečić were relegated to the Montenegrin Second League. Montenegrin Cup winners FK Čelik Nikšić were promoted along with Mornar and Jedinstvo Bijelo Polje.
All figures for stadiums include seating capacity only, as many stadiums in Montenegro have stands without chairs which would otherwise be the actual number of people able to attend football matches not regulated by UEFA or FIFA.
