Asturian Socialist Federation

The Asturian Socialist Federation (Spanish: Federación Socialista Asturiana), often shortened to FSA–PSOE, is the regional section of the Spanish Socialist Workers' Party (PSOE) in the Principality of Asturias. It was formed on 27 January 1901 from the Socialist local groupings of Gijón (formed in 1891), Oviedo (1892), Mieres and Sama de Langreo (1897) and others.

Since the Spanish transition to democracy started in 1975 and since the establishment of the Spanish "State of Autonomies" in 1983, the FSA–PSOE has governed Asturias nearly uninterruptedly from 1983 to 1995, from 1999 to 2011 and again since 2012.
