2012–13 Campionato Sammarinese di Calcio

The 2012–13 Campionato Sammarinese di Calcio season was the twenty-eighth since its establishment.

The league is the uppermost in San Marino, in which the country's top 15 amateur football clubs play.

Tre Penne are the defending league champions, having won their first ever Sammarinese championship last season.

Tre Penne retained their title, defeating ten-man AC Libertas 5–3 on penalties in a repeat of the previous year's play-off final.
