The 1990 Basque parliamentary election was held on Sunday, 28 October 1990, to elect the 4th Basque Parliament, the regional legislature of the Spanish autonomous community of the Basque Country. At stake were all 75 seats in the Parliament, determining the Lehendakari (President of the Basque Country).

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.

Electoral system

The 75 members of the Basque Parliament were elected in 3 multi-member districts, corresponding to the Basque Country's three provinces, using the D'Hondt method and a closed-list proportional representation system. Each district was assigned a fixed set of seats, distributed as follows: Alava (25), Biscay (25) and Gipuzkoa (25).

Voting was on the basis of universal suffrage in a secret ballot. Only lists polling above 5% of valid votes in each district (which include blank ballots—for none of the above) were entitled to enter the seat distribution.
