Next Aragonese regional election

The next Aragonese regional election will be held no later than Sunday, 27 June 2027, to elect the 12th Cortes of the autonomous community of Aragon. All 67 seats in the Cortes will be up for election. If customary practice is maintained, the election will be held on Sunday, 23 May 2027, simultaneously with regional elections in at least seven other autonomous communities and local elections all throughout Spain.

Electoral system
The Cortes of Aragon are the devolved, unicameral legislature of the autonomous community of Aragon, having legislative power in regional matters as defined by the Spanish Constitution and the Aragonese Statute of Autonomy, as well as the ability to vote confidence in or withdraw it from a regional president. 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.

The 67 members of the Cortes of Aragon are elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which includes blank ballots—being applied in each constituency. Seats are allocated to constituencies, corresponding to the provinces of Huesca, Teruel and Zaragoza, with each being allocated an initial minimum of 13 seats and the remaining 28 being distributed in proportion to their populations (provided that the seat-to-population ratio in the most populated province does not exceed 2.75 times that of the least populated one).

As a result of the aforementioned allocation, each Cortes constituency is entitled the following seats:

The use of the D'Hondt method may result in a higher effective threshold, depending on the district magnitude.

Election date
The term of the Cortes of Aragon expires four years after the date of their previous election, unless they are dissolved earlier. The election decree shall be issued no later than the twenty-fifth day prior to the 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. The previous election was held on 28 May 2023, which meant that the legislature's term will expire on 28 May 2027. The election decree shall 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 election date for the Assembly on Sunday, 27 June 2027.

The president has the prerogative to dissolve the Cortes of Aragon and call a snap election, provided that no motion of no confidence is in process and that dissolution does not occur before one year has elapsed since the previous one. 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.

Parliamentary composition
The table below shows the composition of the parliamentary groups in the Cortes at the present time.

Parties and candidates
The electoral law allows for parties and federations registered in the interior ministry, coalitions and groupings of electors to present lists of candidates. Parties and federations intending to form a coalition 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.

Below is a list of the main parties and electoral alliances which will likely contest the election:

Opinion polls
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.
