The 2016–17 Campionato Sammarinese di Calcio season was the 32nd since its establishment. It is the only level in San Marino, in which all the country's 15 amateur football clubs play (there is no relegation). The season began on 9 September 2016 and ended with the play-off final on 20 May 2017. Tre Penne were the defending champions. The fixtures and group compositions were announced on 27 August 2016.[1]
Participating teams
Because there is no promotion or relegation in the league, the same 15 teams who competed in the league last season competed in the league this season.
All teams played twice against the teams within their own group and once against the teams from the other group. This meant that the clubs in the eight-club group played 21 matches each while the clubs in the seven-club group played 20 matches each during the regular season.[4]
The play-offs were played in a double-eliminination format with both group winners earning byes in the first and second round. All matches were decided over one leg with extra time and then penalties used to break ties.
