The 2005 Basque parliamentary election was held on Sunday, 17 April 2005, to elect the 8th Basque Parliament, the regional legislature of the Spanish autonomous community of the Basque Country. All 75 seats in the Parliament were up for election.

The electoral coalition Basque Nationalist Party–Basque Solidarity (PNV–EA) won 29 seats, the Socialist Party of the Basque Country–Basque Country Left (PSE–EE) came second with 18 seats, the People's Party (PP) came in third with 15 seats. The controversial Communist Party of the Basque Homelands (PCTV/EHAK) won 9 seats, having been endorsed by the banned Batasuna party.

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 3% of valid votes—which included blank ballots—was applied in each constituency, with parties not reaching the threshold not taken into consideration for seat distribution.
