The 2010–11 Liga II was the 71st season of the second tier of the Romanian football league system.
A successor team was founded by the merge of Navobi Iași and Tricolorul Breaza and enrolled directly in the second league, due to the vacant place left by Baia Mare.
The new entity was founded by the former owners of Săgeata Stejaru, team which was subsequently enrolled in the lower leagues.
Dunărea Giurgiu signed a partnership with Liga I side Astra Ploiești and started to be its second squad.
At the end of the season, FRF decided that a promotion playoff round would be played between Săgeata Năvodari and Voința Sibiu, third and fourth respectively in each series, following the relegation of five teams from the 2010–11 Liga I.
