A regional election was held in the Community of Madrid on Wednesday, 10 June 1987, to elect the 2nd Assembly of the autonomous community. All 96 seats in the Assembly were up for election. It was held concurrently with regional elections in twelve other autonomous communities and local elections all across Spain, as well as the 1987 European Parliament election.

The Spanish Socialist Workers' Party (PSOE) under Joaquín Leguina lost its overall majority in the Assembly, but remained the largest party. The most notable election result was the Democratic and Social Centre (CDS) breakthrough, emerging as the third largest party at the expense of all other parties in the regional parliament. The People's Alliance (AP) of newly elected AP Madrid leader Alberto Ruiz-Gallardón remained static, maintaining its position as the second largest party, while United Left (IU), a coalition of the Communist Party of Spain and other left-wing political forces, slipped to fourth place.

In the aftermath of the election, the CDS chose to abstain in the investiture voting in order to allow the PSOE to continue to govern in minority.

Under the 1983 Statute of Autonomy, the Assembly of Madrid was the unicameral legislature of the homonymous autonomous community, having legislative power in devolved matters, as well as the ability to vote confidence in or withdraw it from a regional president.^[2]

Voting for the Assembly was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in the Community of Madrid and in full enjoyment of their political rights, provided that they were not sentenced—by a final court ruling—to deprivation of the right to vote, nor being legally incapacitated.^[3][4][5]

The Assembly of Madrid was entitled to one seat per each 50,000 inhabitants or fraction greater than 25,000. All members were elected in a single multi-member constituency—corresponding to the autonomous community's territory—using the D'Hondt method and a closed list proportional voting system, with an electoral threshold of five percent of valid votes (which included blank ballots) being applied regionally.^[3][6] As a result of the aforementioned allocation, the Assembly was entitled to 96 seats, based on the official population figures resulting from the latest revision of the municipal register (as of 1 January 1986).^[7]

The law did not provide for by-elections to fill vacated seats; instead, any vacancies that occurred after the proclamation of candidates and into the legislative term were to be covered by the successive candidates in the list and, when required, by the designated substitutes.^[8][9]

The term of the Assembly of Madrid expired four years after the date of its previous ordinary election. The election decree was required to be issued no later than the twenty-fifth day prior to the scheduled date of expiry of parliament and published on the following day in the Official Gazette of the Community of Madrid (BOCM), with election day taking place between the fifty-fourth and the sixtieth day from publication.^[3][10][11] The previous election was held on 8 May 1983, which meant that the legislature's term would have expired on 8 May 1987. The election decree was required to be published in the BOCM no later than 14 April 1987, with the election taking place up to the sixtieth day from publication, setting the latest possible date for election day on Saturday, 13 June 1987.

The Assembly of Madrid could not be dissolved before the date of expiry of parliament, except in the event of an investiture process failing to elect a regional president within a two-month period from the first ballot. In such a case, the Assembly was to be automatically dissolved and a snap election called, with elected deputies merely serving out what remained of their original four-year term.^[12]

The election to the Assembly of Madrid was officially called on 14 April 1987 with the publication of the corresponding decree in the BOCM, setting election day for 10 June and scheduling for the chamber to reconvene on 2 July.^[7]

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 ahead of an election were required to inform the relevant electoral commission within ten days of the election call, whereas groupings of electors needed to secure the signature of at least 0.5 percent of the electorate in the Community of Madrid, disallowing electors from signing for more than one list of candidates.^[8][13]

Below is a list of the main parties and electoral alliances which contested the election:

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.

The table below lists weighted voting intention estimates. Refusals are generally excluded from the party vote percentages, while question wording and the treatment of "don't know" responses and those not intending to vote may vary between polling organisations. When available, seat projections determined by the polling organisations are displayed below (or in place of) the percentages in a smaller font; 49 seats were required for an absolute majority in the Assembly of Madrid (48 in the 1983 election).
