The Sammarinese Christian Democratic Party (Italian: Partito Democratico Cristiano Sammarinese, PDCS) is a Christian-democratic[1] political party in San Marino.

For the 2008 general election the party was part of the Pact for San Marino coalition and gave hospitality in its list to some candidates of the Euro-Populars for San Marino and Arengo and Freedom.

The electoral coalition won 35 seats out of 60 in the Grand and General Council in the Sammarinese parliamentary election, 2008 gaining 54.22% of the national vote and a governmental majority of 5, becoming the new government of San Marino.

Ernesto Benedettini became one of the two Joint Captains Regent of San Marino.

A political crisis in 2011 dissolved the old majority, and the PDCS formed a government of national unity with the Party of Socialists and Democrats, whose predecessors worked with the PDCS for decades, so restoring a political formula which led San Marino, and Italy, during the second half of the 20th century.
