The Campionato Sammarinese di Calcio 2019/20 was the 35th season of the San Marinese Football League . It started on September 20, 2019, the last games took place on February 23, 2020. Due to the COVID-19 pandemic , the season was initially suspended and declared over on June 16, 2020. The national football association declared league leaders SP Tre Fiori champions on June 23, 2020 . At the time of the abandonment, a good half of the games had been played in the second group phase.
In the basic round, the teams played in two equal groups of eight and seven teams respectively. Each team met the teams in its own group once. In the second group phase, the four best-placed teams in each group competed in group 1, the rest in group 2. In the second group phase, all teams should compete against each other twice. Due to the cancellation during the second group phase, the playoffs planned afterwards were also no longer applicable.
Since there is only one soccer league in San-Marino, there is no promotion or relegation of individual teams. Therefore, the same clubs took part as in the previous season. The 15 teams were drawn into the two groups shortly before the start of the season.
