The 1990 Basque regional election was held on Sunday, 28 October 1990, to elect the 4th Parliament of the Basque Autonomous Community. All 75 seats in the Parliament were up for election.

The Basque Nationalist Party (EAJ/PNV) won 22 seats, the Socialist Party of the Basque Country (PSE–PSOE) came second with 16 seats, People's Unity (HB) came third with 13 seats and Basque Solidarity (EA) won 9 seats. The People's Party (PP) and Basque Country Left (EE) each won 6 seats.

The approval of a new electoral law in 1990 replaced the previous legislation that in force since 1983 and accommodated election procedures to the national General Electoral System Organic Law of 1985, with few changes to the electoral system. 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 included blank ballots, as introduced by the 1990 law—was applied in each constituency, with parties not reaching the threshold not taken into consideration for seat distribution.
