The 2009–10 Montenegrin Second League (Serbian: Druga Crnogorska Liga / Друга црногорска лига) was the 4th season since its establishment.
Twelve teams participate in this league. The top team directly qualifies for the Montenegrin First League while the second and third teams contest in a two matches playoff against the 11th and 12th team from the First League. The two bottom-placed teams are relegated to the Third League, to be replaced by the two winners of the Third League promotion play-off.
