The 1986 Basque regional election was held on Sunday, 30 November 1986, to elect the 3rd Parliament of the Basque Autonomous Community. All 75 seats in the Parliament were up for election.

The Socialist Party of the Basque Country (PSE–PSOE) won 19 seats, the Basque Nationalist Party (EAJ/PNV) came second with 17 seats, People's Unity (HB) and Basque Solidarity (EA), a PNV split, each won 13 seats, and Basque Country Left won 9 seats.

The Basque Parliament was elected using the D'Hondt method and a closed list proportional representation. Under the regional Statute of Autonomy, all three Basque historical territories—the provinces—were to constitute multi-member districts, being assigned an equal number of seats each. The electoral law set this to a fixed-number of 25, for a total of 75 seats. A threshold of 5% of valid votes—which, unlike other electoral legislation in Spain, did not include blank ballots—was applied in each constituency, with parties not reaching the threshold not taken into consideration for seat distribution.

Voting was on the basis of universal suffrage, with all residents over eighteen and in the full enjoyment of all political rights entitled to vote. Concurrently, residents meeting the previous criteria and not involved in any cause of ineligibility were eligible for the Parliament. Groups of electors were required to obtain the signatures of at least 500 registered electors in a particular district in order to be able to field candidates.
