2003 San Marino local elections

The election in Borgo Maggiore was declared invalid, as the turnout quorum was not reached.

The number of seats was determined by law: the city councils of Chiesanuova, Faetano and Montegiardino were composed of eight members; the councils of Acquaviva, Borgo Maggiore, City of San Marino, Domagnano, Fiorentino and Serravalle were composed of 10 members.

Voters elected a list and were allowed to give up to two preferential votes.

Seats were allocated with the d'Hondt method if the winner had obtained at least 60% of the votes.
