A regional election will be held in Navarre on 23 May 2027 to elect the 12th Parliament of the chartered community. All 50 seats in the Parliament will be up for election. It will be held concurrently with regional elections in at least six other autonomous communities and local elections all across Spain.

Overview Under the 1982 Reintegration and Improvement of the Chartered Regime, the Parliament of Navarre is the unicameral legislature of the homonymous chartered community, having legislative power in devolved matters, as well as the ability to grant or withdraw confidence from a regional president.. The electoral and procedural rules were supplemented by national law provisions..

Date The term of the Parliament of Navarre expires four years after the date of its previous election, unless it is dissolved earlier. If no snap election is called before the last year of the legislative term, the election decree shall be issued no later than 54 days before the scheduled election date and published on the following day in the Official Gazette of Navarre (BON), with election day taking place on the fourth Sunday of May four years after the previous election.; ( by ). The previous election was held on 28 May 2023, setting the latest possible date for election day on the fourth Sunday of May four years later, which is 23 May 2027.

The regional president has the prerogative to dissolve the Parliament of Navarre at any given time and call a snap election, provided that no motion of no confidence is in process, no nationwide election is due and some time requirements are met: namely, that dissolution does not occur either during the first legislative session or during the last year of parliament before its planned expiration, nor before one year after a previous one under this procedure.; . In the event of an investiture process failing to elect a regional president within a three-month period from election day, the Parliament shall be automatically dissolved and a fresh election called..

Electoral system Voting for the Parliament is based on universal suffrage, comprising all Spanish nationals over 18 years of age, registered in Navarre and with full political rights, provided that they have not been deprived of the right to vote by a final sentence.; ( by ).

The Parliament of Navarre has a minimum of 40 and a maximum of 60 seats, with electoral provisions fixing its size at 50. All are elected in a single multi-member constituency—corresponding to the chartered community's territory—using the D'Hondt method and closed-list proportional voting, with a three percent-threshold of valid votes (including blank ballots) regionally.; .

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. ( by ).

Parties and candidates 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 Navarre, disallowing electors from signing for more than one list. ( by ). Amendments in 2024 required a balanced composition of men and women in the electoral lists through the use of a zipper system..

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.
