Locations of the 1977-78 Montenegrin Republic League teams
Sixteen teams participated in the 1977-78 season. Among the clubs which didn't play in the previous season were Jedinstvo (relegated from Yugoslav Second League) and three best teams from Regional leagues - Ivangrad, Štampar and Zabjelo.[2]
Jedinstvo won the title with a gap of five points over second place, OFK Petrovac.[3] After the decision of reducing number of participants in 1978–79, the league saw five teams relegated to the bottom tier as the league was reduced to 14 teams.
