2019−20 Coppa Italia Serie D

The 2019−20 Coppa Italia Serie D was the 21st edition of Coppa Italia Serie D. Due to the COVID-19 pandemic in Italy, on 20 May 2020, Lega Nazionale Dilettanti decided not to complete the competition.

Format
All rounds of the event, with the exception of the semi-finals, are a single-match direct elimination. For these matches, in the event of a draw at the end of the 90 minute regulation time, penalty shootout is used to determine the winning team (no extra time is played). The home factor is determined by drawing lots in the preliminary round, in the first round and in round 64. In the round of 32, in the round of 16 and in the quarter-finals, however, the team that played away in the previous round plays at home. The other way around, proceeding with the draw only in the case of a match between two teams that have both played at home, or both away, in the previous round, the final is instead played at a neutral ground. The semi-finals are organized in home and away matches, with a draw to determine the order of the fields and with the application of the away goal rule. In the return matches there are no extra times but direct penalties in the event of a score that determines a draw in both overall goals and away goals. The match schedule is guided by criteria of geographical proximity.
