Next Castilian-Leonese regional election

Under the 2007 Statute of Autonomy, the Cortes of Castile and León is the unicameral legislature of the homonymous autonomous community, having legislative power in devolved matters, as well as the ability to grant or withdraw confidence from a regional president.^[5] The electoral and procedural rules are supplemented by national law provisions.^[6]

The term of the Cortes of Castile and León expires four years after the date of its previous election, unless it is dissolved earlier. The election decree shall be issued no later than 25 days before the scheduled expiration date of parliament and published on the following day in the Official Gazette of Castile and León (BOCYL), with election day taking place 54 days after the decree's publication.^[7] The previous election was held on 15 March 2026, which means that the chamber's term will expire on 15 March 2030. The election decree shall be published in the BOCYL no later than 19 February 2030, setting the latest possible date for election day on 14 April 2030.

The regional president has the prerogative to dissolve the Cortes of Castile and León at any given time and call a snap election, provided that no motion of no confidence is in process and that dissolution does not occur either during the first legislative session or before one year after a previous one.^[8] In the event of an investiture process failing to elect a regional president within a two-month period from the first ballot, the Cortes shall be automatically dissolved and a fresh election called.^[9]

Voting for the Cortes is based on universal suffrage, comprising all Spanish nationals over 18 years of age, registered in Castile and León and with full political rights, provided that they had not been deprived of the right to vote by a final sentence.^[10]

The Cortes of Castile and León has three seats per each multi-member constituency—corresponding to the provinces of Ávila, Burgos, León, Palencia, Salamanca, Segovia, Soria, Valladolid and Zamora—plus one additional seat per each 45,000 inhabitants or fraction above 22,500. All are elected using the D'Hondt method and closed-list proportional voting, with a three percent-threshold of valid votes (including blank ballots) in each constituency.^[11] The use of this electoral method may result in a higher effective threshold depending on district magnitude and vote distribution.^[12]

As a result of the aforementioned allocation, each Cortes constituency would be entitled the following seats (as of 11 December 2025):^[d]

The law does not provide for by-elections to fill vacant seats; instead, any vacancies arising after the proclamation of candidates and during the legislative term will be filled by the next candidates on the party lists or, when required, by designated substitutes.^[14]

The electoral law allows for parties and federations registered in the interior ministry, alliances and groupings of electors to present lists of candidates. Parties and federations intending to form an alliance are required to inform the relevant electoral commission within 10 days of the election call, whereas groupings of electors need to secure the signature of at least one percent of the electorate in the constituencies for which they seek election, disallowing electors from signing for more than one list.^[15] Additionally, a balanced composition of men and women was required in the electoral lists through the use of a zipper system.^[16]
