Voting for the Cortes is on the basis of universal suffrage, which comprises all nationals over 18 years of age, registered in Aragon and in full enjoyment of their political rights, provided that they are not sentenced—by a final court ruling—to deprivation of the right to vote.[3][4][5]
The Cortes of Aragon are entitled to a minimum of 65 and a maximum of 80 seats, with the electoral law setting its size at 67. All members are elected in three multi-member constituencies—corresponding to the provinces of Huesca, Teruel and Zaragoza, with each being allocated an initial minimum of 14 seats and the remaining 25 being distributed in proportion to their populations (provided that the seat-to-population ratio in the most populated province does not exceed three times that of the least populated one)—using the D'Hondt method and a closed listproportional voting system, with an electoral threshold of three percent of valid votes (which includes blank ballots) being applied in each constituency.[6][7] The use of the electoral method may result in a higher effective threshold based on the district magnitude and the distribution of votes among candidacies.[8]
As a result of the aforementioned allocation, each Cortes constituency was entitled the following seats:[9]
The law does not provide for by-elections to fill vacated seats; instead, any vacancies that occur after the proclamation of candidates and into the legislative term will be covered by the successive candidates in the list and, when required, by the designated substitutes.[10][11]
Election date
The term of the Cortes of Aragon expired four years after the date of their previous election, unless they were dissolved earlier. The election decree was required to be issued no later than the twenty-fifth day prior to the scheduled date of expiry of parliament and published on the following day in the Official Gazette of Aragon (BOA), with election day taking place on the fifty-fourth day from publication.[3][12][13] The previous election was held on 28 May 2023, which meant that the legislature's term would have expired on 28 May 2027. The election decree was required to be published in the BOA no later than 4 May 2027, with the election taking place on the fifty-fourth day from publication, setting the latest possible date for election day on Sunday, 27 June 2027.
The regional president had the prerogative to dissolve the Cortes of Aragon and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year had elapsed since the previous one.[12][14] In the event of an investiture process failing to elect a regional president within a two-month period from the first ballot, the Cortes were to be automatically dissolved and a fresh election called.[15]
Speculation emerged in September 2025 that the national leadership of the People's Party (PP) was planning to advance the elections in Aragon and Extremadura (and possibly the Balearic Islands) to make them take place near or concurrently with the Castilian-Leonese election scheduled for early 2026, in an electoral "Super Sunday".[16][17][18] While the alleged justification would be the regional governments' failure to approve their 2026 budgets, the true motive was attributed to PP plans—not without risk—to turn the simultaneous election call into a referendum on the national government of Prime Minister Pedro Sánchez.[19][20] Regional president Jorge Azcón ruled out any plans of a joint election call with other regions,[21][22] with his government's allegedly focused on avoiding an election.[23][24] Tensions between PP and Vox remained high,[25] and a controversy over the dismissal of a Vox parliamentary advisor for online hate speech prompted the breakup of budget negotiations on 21 October.[26][27][28] Vox was reportedly willing to take public blame for forcing early elections in Aragon and Extremadura.[29][30] Azcón's government rejected an immediate election call following the announcement of a snap Extremaduran election for 21 December 2025,[31][32][33] but this was attributed to him having his own timetable—unlike in Extremadura, budgetary procedures had not yet begun in Aragon[34][35]—rather than a lack of willingness for a 2026 election.[36][37][38] Throughout November 2025, Azcón hinted at a failure in budget negotiations leading to an early parliament dissolution,[39][40] with a possible election date being considered for February 2026, so as to prevent a simultaneous call with Castile and León in March.[41][42] February was hinted as the most likely month for a snap election,[43][44][45] with various Spanish outlets confirming on 12 December that the dissolution decree would be signed the next Monday for an election to be held on 8 February.[46][47][48]
The Cortes of Aragon were officially dissolved on 16 December 2025 with the publication of the dissolution decree in the BOA, setting election day for 8 February and scheduling for the chamber to reconvene on 3 March.[9][49]

People's Parliamentary Group in the Cortes of Aragon
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 ahead of an election are required to inform the relevant electoral commission within ten 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 of candidates.[52][53] Amendments to the electoral law in 2024 increased requirements for a balanced composition of men and women in the electoral lists through the use of a zipper system.[54]
Below is a list of the main parties and electoral alliances which will likely contest the election:
8 February: Election day (polling stations open at 9am and close at 8pm or once voters present in a queue at/outside the polling station at 8pm have cast their vote); provisional vote counting.
11 February: Start of general vote counting, including CERA votes.
14 February: Deadline for the general vote counting.
23 February: Deadline for the proclamation of elected members.
10 March: Deadline for the reconvening of parliament.[12]
4 April: Deadline for the publication of definitive election results in the BOA.
The tables below list opinion polling results in reverse chronological order, showing the most recent first and using the dates when the survey fieldwork was done, as opposed to the date of publication. Where the fieldwork dates are unknown, the date of publication is given instead. The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour. If a tie ensues, this is applied to the figures with the highest percentages. The "Lead" column on the right shows the percentage-point difference between the parties with the highest percentages in a poll.

Voting intention estimates
The table below lists weighted voting intention estimates. Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between polling organisations. When available, seat projections determined by the polling organisations are displayed below (or in place of) the percentages in a smaller font; 34 seats are required for an absolute majority in the Cortes of Aragon.
