Overview Under the 1982 Statute of Autonomy, the Cortes of Castilla–La Mancha 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.. The electoral and procedural rules are supplemented by national law provisions..

Date The term of the of Castilla–La Mancha expires 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 shall be issued no later than 54 days before the scheduled election date and published on the following day in the Official Journal of Castilla–La Mancha (DOCM).; ( by ). The previous election was held on 28 May 2023, setting the 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 of Castilla–La Mancha 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, with elected lawmakers serving the remainder of its original four-year term.; .

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

The has a minimum of 25 and a maximum of 35 seats, with electoral provisions fixing its size at 33. All are elected in five multi-member constituencies—corresponding to the provinces of Albacete, Ciudad Real, Cuenca, Guadalajara and Toledo, each of which is assigned an initial minimum of three seats and the remaining 18 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 may result in a higher effective threshold depending on district magnitude and vote distribution.

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

Seats Constituencies 9 Toledo 7 Ciudad Real 6 Albacete, Guadalajara 5 Cuenca
