León is one of the nine constituencies () represented in the Cortes of Castile and León, the regional legislature of the Autonomous Community of Castile and León. The constituency currently elects 14 deputies. Its boundaries correspond to those of the Spanish province of León. The electoral system uses the D'Hondt method and closed-list proportional representation, with a minimum threshold of three percent.

Electoral system The constituency was created as per the Statute of Autonomy of Castile and León of 1983 and was first contested in the 1983 regional election. The Statute provided for the nine provinces in Castile and León—Ávila, Burgos, León, Palencia, Salamanca, Segovia, Soria, Valladolid and Zamora—to be established as multi-member districts in the Cortes of Castile and León, with this regulation being maintained under the 1987 regional electoral law. Each constituency is entitled to an initial minimum of three seats, with one additional member per each 45,000 inhabitants or fraction greater than 22,500.

Voting is on the basis of universal suffrage, which comprises all nationals over eighteen, registered in Castile and León and in full enjoyment of their political rights. Amendments to the electoral law in 2011 required for Castilian-Leonese people abroad to apply for voting before being permitted to vote, a system known as "begged" or expat vote () which was abolished in 2022. Seats 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. The use of the D'Hondt method might result in a higher effective threshold, depending on the district magnitude.

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—fifteen before 1985—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—one-thousandth of the electorate, with a compulsory minimum of 500 signatures, until 1985—disallowing electors from signing for more than one list of candidates.
