Regional elections will be held in Spain during 2027 to elect the regional parliaments of at least six of the seventeen autonomous communities: Andalusia and Castile and León; and the two autonomous cities of Ceuta and Melilla. At least 331 of 1,220 seats in the regional parliaments will be up for election, as well as the 50 seats in the regional assemblies of the autonomous cities. The elections will held on 23 May (concurrently with local elections all across the country). Additional elections may be held throughout the year in the event of early dissolutions being triggered in other regions.
Determination of election day varies depending on the autonomous community. Typically, most autonomous communities hold their elections on the fourth Sunday of May every four years, concurrently with nationwide local elections, while others have their own, separate electoral cycles. In some cases, regional presidents have the prerogative to dissolve parliament and call for extra elections at a different time, but newly elected assemblies are restricted to serving out what remain of their previous four year-terms without altering the period to their next ordinary election. In other casesâÂÂAndalusia (since 1994), Aragon (2007), the Balearic Islands (2007), the Basque Country (1981), the Canary Islands (2018), Castile and León (2007), Catalonia (1985), Extremadura (2011), Galicia (1985), Navarre (2010) and the Valencian Community (2006)âÂÂthe law grants regional presidents the power to call snap elections resulting in fresh four-year parliamentary terms.
