The 2009–10 Serie D was the sixty-second edition of the top level Italian non-professional football championship. It represented the fourth tier in the Italian football league system. It consisted of 167 divided into six 18-team divisions, one 19-team division and two 20-team divisions.

The regular Serie D season started September 6, 2009. Each team played two matches against every other team in its own division; a total of 34 matches for 18-team divisions, 36 matches for the 19-team divisions, and 38 matches for the 20-team division. The nine division winners were automatically promoted to Lega Pro Seconda Divisione for the 2009-10 season, while the two last-placed teams are automatically relegated to Eccellenza.

After the regular season is complete, teams placed 6th-last through to 3rd-last in each division play a double-leg series (6th-last vs 3rd-last, 5th-last vs 4th-last) where the winners remain in Serie D the following season and the two losers are also relegated to Eccellenza for a total of 4 relegations in each division, 36 in total for the league.There are no playoffs if the difference between two teams is bigger than eight points.

The nine division winners enter a tournament to determine the over-all Serie D champion and is awarded the Scudetto Dilettanti.

Teams placed second through fifth in each division enter a playoff tournament after the regular season as well. Eventually, a final game determines which team finishes first and which teams comes in second in this 36-team playoff, and these teams may be bumped up to Lega Pro Seconda Divisione if one or more current Seconda Divisione teams runs into financial difficulties or is penalized.
