Lega Pro Prima Divisione was the third highest football league in Italy. It consisted of 33 teams, divided geographically into two divisions of 16 and 17 teams for group A and B respectively. Until 2008 it was known as Serie C1.^[1]

Before the 1978–79 season there were only three leagues of professional football in Italy, the third being Serie C. In 1978, it was decided to split Serie C into Serie C1 and Serie C2. Serie C2, the fourth highest professional league in the Italian system, was also renamed in 2008 and was called Lega Pro Seconda Divisione.^{[citation needed]} The reform, already decided by the FIGC led to the reunification with the second division starting from 2014-2015 and with the subsequent rebirth of the third division championship organized by the pro league with 60 teams divided into three groups of 20 in Lega Pro.^{[citation needed]}

In each division, two teams were promoted to Serie B, and three teams were relegated to Lega Pro Seconda Divisione. In total, the league promoted 4 teams to Serie B and relegated 6 teams to Seconda Divisione.

The team finishing first in the regular season was directly promoted to Serie B, while teams placing 2nd to 5th were entered into a play-off semi-final for the chance of gaining the second promotional spot for that particular division.
