A regional election was held in Asturias on 28 May 2023 to elect the 12th General Junta of the autonomous community. All 45 seats in the General Junta were up for election. It was held concurrently with regional elections in eleven other autonomous communities and local elections all across Spain.

Overview Under the 1981 Statute of Autonomy, the General Junta of the Principality of Asturias was 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.. The electoral and procedural rules were supplemented by national law provisions..

Date The term of the General Junta of the Principality of Asturias expired four years after the date of its previous election., with election day being fixed for the fourth Sunday of May every four years. The election decree was required to be issued no later than 54 days before the scheduled election date and published on the following day in the Official Gazette of the Principality of Asturias (BOPA).; ( by ). The previous election was held on 26 May 2019, setting the date for election day on the fourth Sunday of May four years later, which was 28 May 2023.

The regional president had the prerogative to dissolve the General Junta of the Principality of Asturias at any given time and call a snap election, provided that no motion of no confidence was in process, no nationwide election was due and some time requirements were met: namely, that dissolution did 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.; . In the event of an investiture process failing to elect a regional president within a two-month period from the first ballot, the General Junta was to be automatically dissolved and a fresh election called. Any snap election held as a result of these circumstances did not alter the date of the chamber's next ordinary election, with elected lawmakers serving the remainder of its original four-year term.; .

The election to the General Junta of the Principality of Asturias was officially called on 4 April 2023 with the publication of the corresponding decree in the BOPA, setting election day for 28 May..

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

The General Junta had a minimum of 35 and a maximum of 45 seats, with electoral provisions fixing its size at the latter number. All were elected in three multi-member constituencies—corresponding to sub-provincial divisions, each of which was assigned an initial minimum of two seats and the remaining 39 distributed in proportion to population—using the D'Hondt method and closed-list proportional voting, with a three percent-threshold of valid votes (including blank ballots) in each constituency.; . The use of this electoral method resulted in a higher effective threshold depending on district magnitude and vote distribution.

As a result of the aforementioned allocation, each General Junta constituency (comprising the municipalities indicated below) was entitled the following seats:; .

The law did not provide for by-elections to fill vacant seats; instead, any vacancies arising after the proclamation of candidates and during the legislative term were filled by the next candidates on the party lists or, when required, by designated substitutes. ( by ).

Parties and candidates The electoral law allowed 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 were required to inform the relevant electoral commission within 10 days of the election call, whereas groupings of electors needed to secure the signature of at least one percent of the electorate in the constituencies for which they sought election, disallowing electors from signing for more than one list. ( by ). Additionally, a balanced composition of men and women was required in the electoral lists, so that candidates of either sex made up at least 40 percent of the total composition..
