2006–07 Serie C1

At the same time, teams placed 14th to 17th entered a playout for the right to remain in Serie C1 the following season.

As usual, Serie C1 was composed by two divisions, whose teams were divided geographically.

Division C1/A was mainly composed by Northern Italy teams, whereas Division C1/B included mostly Central and Southern Italy teams.

No teams from the major islands of Sardinia or Sicily took part in the 2006–07 Serie C1, as the only two eligible to participate in it, Gela and Sassari Torres, were both omitted due to financial troubles.

Teams finishing first in the regular season, plus one team winning the playoff round from each division were promoted to Serie B; teams finishing last in the regular season, plus two relegation playoff losers from each division were relegated to Serie C2.
