A regional election was held in Navarre on 10 June 1987 to elect the 2nd Parliament of the chartered community. All 50 seats in the Parliament 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 then-incumbent President Gabriel Urralburu, won the election for a second consecutive term, albeit with a diminished share of the vote (27.7%, losing nearly 8 percentage points from 1983) and losing 5 seats. The centre-right spectrum stood divided to the election: the Navarrese People's Union (UPN) maintained its second place with 24.5% and 14 seats (gaining one); the Foral Democrat Union (UDF), an alliance between the People's Democratic Party (PDP) and the Liberal Party (PL), formed after the breakup of the People's Coalition, obtained 6.2% and 3 seats. The People's Alliance (AP) suffered from this division and fell to 7th place (4.2% and 2 seats).

The Democratic and Social Centre (CDS), the party of former Spanish Prime Minister Adolfo Suárez, benefitted from this division and finished fourth, gaining 4 seats. Meanwhile, the left-wing Herri Batasuna (HB) also improved its position from 1983 and scored one of the best results for the abertzale left in Navarre. Eusko Alkartasuna (EA), a split from the Basque Nationalist Party (PNV) formed in 1986 from PNV dissidents, entered the Parliament with 4 seats, while the small Euskadiko Ezkerra also entered for the first time.

Overview Under the 1982 Reintegration and Improvement of the Chartered Regime, the Parliament of Navarre was the unicameral legislature of the homonymous chartered 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 Parliament of Navarre expired four years after the date of its previous ordinary election. The election decree was required to be issued no later than 25 days before the scheduled expiration date of parliament and published on the following day in the Official Gazette of Navarre (BON), with election day taking place between 54 and 60 days after the decree's publication.; ( by ). The previous election was held on 8 May 1983, which meant that the chamber's term would have expired on 8 May 1987. The election decree was required to be published in the BON no later than 14 April 1987, setting the latest possible date for election day on 13 June 1987.

The Parliament of Navarre could not be dissolved before the expiration date of parliament..

The election to the Parliament of Navarre was officially called on 14 April 1987 with the publication of the corresponding decree in the BON, setting election day for 10 June and scheduling for the chamber to reconvene on 4 July..

Electoral system Voting for the Parliament was based on universal suffrage, comprising all Spanish nationals over 18 years of age, registered in Navarre and with full political rights, provided that they had not been deprived of the right to vote by a final sentence, nor were legally incapacitated.; ( by ).

The Parliament of Navarre had a minimum of 40 and a maximum of 60 seats, with electoral provisions fixing its size at 50. All were elected in a single multi-member constituency—corresponding to the chartered community's territory—using the D'Hondt method and closed-list proportional voting, with a three percent-threshold of valid votes (including blank ballots) regionally.; .

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 ).

Opinion polls 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.

Voting intention estimates 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; 26 seats were required for an absolute majority in the Parliament of Navarre.
