The 2005–06 Divizia B was the 66th season of the second tier of the Romanian football league system.
The format has been maintained to three series, each of them consisting of 16 teams. At the end of the season, the winners of the series promoted to Divizia A and the last six places from all the series relegated to Divizia C. A promotion play-off was played between the runners-up of the Divizia B series to decide the fourth promoted team. A special ranking was made between the 10th place teams of every series and the team with the worst ranking in this standing was relegated, as well. These changes in promotion and relegation rules were made because starting with the next season, Romanian football league system was reformed.[1] [2]

In the following season, the Liga I was expanded from 16 teams to 18 teams, therefore the Romanian Football Federation decided that a promotion playoff group would be played at the end of the season, between the second placed teams from each series of the Liga II, in order to establish the fourth promoted team (in exchange to the two teams relegated from the Liga I). The winner of this group, Unirea Urziceni, promoted to the Liga I, along with the three winners of the series.
At the end of the season, a special table was made between 10th places from the 3 series. The last team in this table was also relegated in the Liga III. In this table, 10th place teams are included without the points obtained against teams that relegated in their series.
