The Sardinian Reformers (Italian: Riformatori Sardi, RS) is a regionalist[1] and liberal-conservative[1] political party in Sardinia, led by Michele Cossa.

The party, which has always been part of the centre-right at the Sardinian regional level, is a keen supporter of the free market, competition, globalization and a two-party system.

When the Segni Pact entered The Olive Tree centre-left coalition in the run-up for the 1996 general election (through Italian Renewal), the RS gained some independence from the mother-party, and, when at the 1999 European Parliament election Segni formed a joint electoral list with National Alliance, some of their members looked closer to Forza Italia.

In 2003 the RS contributed to the foundation of the new national party of Mario Segni named Pact of Liberal Democrats.

The RS won 6.8% of the vote (having their strongholds in the provinces of Oristano and Olbia-Tempio, where they gained 10.0 and 8.7%, respectively[3]) and five regional councillors (including Cossa) plus one (Franco Meloni, a former leading member of the Sardinian Action Party) elected in Cappellacci's regional list.
