The 2015–16 Liga Națională season was the 66th season of the Liga Națională, the highest professional basketball league in Romania. CSM U Oradea won its first national championship this season.[1]
Defending champion Asesoft Ploiești left the league due to its financial trouble to play in the first league.[2] Meanwhile, Universitatea Cluj and Timba Timișoara were relegated to the Liga I as last qualified teams of the previous season. Dinamo București and Phoenix Galați promoted as champions and runners-up from the 2014–15 Liga I season.
