The 1987 Spanish regional elections were held on Wednesday, 10 June 1987 in Spain, to elect the regional parliaments of 13 of the 17 autonomous communities: Aragon, Asturias, the Balearic Islands, the Canary Islands, Cantabria, Castile-La Mancha, Castile and León, Extremadura, Madrid, Murcia, Navarre, La Rioja and the Valencian Community. Andalusia, Catalonia, Galicia and the Basque Country did not held elections that day because they had separate electoral cycles. Municipal elections were held throughout Spain the same day.
The Spanish Socialist Workers' Party (PSOE) remained the largest party overall and in most regional parliaments, but lost 742,000 votes, nearly 10 percentage points and many of the absolute majorities it had obtained four years previously. As a result, several centre-right coalitions and alliances were able to oust the Socialists from government in 4 out of the 12 regional executives it held previous to the election.
The main national opposition party, the People's Alliance (AP), having suffered from an internal crisis and the breakup of the People's Coalition in 1986, also lost support compared to the previous election. Its former allies, the People's Democratic Party (PDP) and the Liberal Party (PL), stood separately in the regional elections but remained unable to capitalize on the AP's losses.
Benefitting from the two main parties' fall was the Democratic and Social Centre (CDS), a party led by the former Spanish Prime Minister Adolfo Suarez, achieving over 14% of the vote and more than 100 regional parliamentary seats. United Left (IU), a coalition made up by the Communist Party of Spain (PCE) and other minor left-wing groups, remained static at the PCE's 1983 result at 6% and 26 seats.
