The 2015–16 Liga II was the 76th season of the Liga II, the second tier of the Romanian football league system. The season began on 29 August. The 28 teams were divided in two series (with 14 teams each). The regular season was played in a round-robin tournament. The first six teams from each series played a play-off for promotion to Liga I. Because of switching to a system with just one series of 22 teams from next season, there will be 11 teams relegated from Liga II this year. After the regular season, the last two teams in each series relegated to Liga III; the last 3 teams in each play-out pool also relegated, while the 3rd placed teams in the play-out faced off in a game that determined the 11th relegated team.
