The Prva B Liga, also known as Second Montenegrin League, is the second-tier of domestic basketball league system in Montenegro.

During its first season, Prva B Liga (which means First B League) was organized through two groups.

The winner gains promotion to the Montenegrin Basketball League and the runner-up plays with the bottom five teams of the regular season of the First Erste League.

The bottom two teams from the play-out group relegate to the Second League.
