Zaragoza is one of the three constituencies () represented in the Cortes of Aragon, the regional legislature of the Autonomous Community of Aragon. The constituency currently elects 35 deputies. Its boundaries correspond to those of the Spanish province of Zaragoza. 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 established under the Statute of Autonomy of Aragon of 1982 and was first contested in the 1983 regional election. The Statute (reformed in 2007) provides for the three provinces in Aragon—Huesca, Teruel and Zaragoza—to be set as multi-member constituencies in the , each of which is assigned an initial minimum of 14 seats—13 until 2023—and the remaining ones are distributed in proportion to population (with the seat-to-population ratio in the most populated province not exceeding three times—2.75 times until 2023—that of the least populated one).; ; . The exception was the 1983 election, when each constituency was allocated a fixed number of seats.; . Seats are elected 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. 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 are filled by the next candidates on the party lists or, when required, by designated substitutes.

Voting is based on universal suffrage, comprising all Spanish nationals over 18 years of age, registered in the constituency and with full political rights.; ; ( by ; by ). Amendments in 2011 required non-resident citizens to apply for voting, a system known as "begged" voting (), which was abolished in 2022 and attributed responsibility for a major decrease in the turnout of Spaniards abroad during the years it was in force.. Additionally, those legally incapacitated were also barred from voting before amendments in 2018 granted them the right to vote.
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—15 before 1985—whereas groupings of electors need to secure the signature of at least two percent of the electorate in the constituencies for which they seek election (before 1985 this was one permille, with a compulsory minimum of 500 signatures), disallowing electors from signing for more than one list. ( by ; by ). Amendments in 2007 required a balanced composition of men and women in the electoral lists, so that candidates of either sex made up at least 40 percent of the total composition; amendments in 2024 reinforced these through the use of a zipper system..
