The Socialist Party of Majorca (Catalan: Partit Socialista de Mallorca, PSM; IPA: [pəɾˈtit sosi.əˈlistə ðə məˈʎɔɾkə]), officially PSM–Entesa after the incorporation of Entesa per Mallorca (ExM) in February 2013,[1] is a political party in Majorca, Spain.

The PSM defines itself as socialist, environmentalist, and Catalan nationalist, from a Majorcan point of view.

It advocates the self-determination and the freedom of the Balearic Islands, with social justice, to increase the identity and the self-government of the archipelago.

In 2011, the Bloc broke and the party decided to form an electoral coalition with IniciativaVerds (IV) and ExM for the regional election.

Later that year, the coalition was enlarged by the addition of the new ecologist party eQuo, and participated in the 2011 general election, getting 31,378 votes and no representation.
