The 2008 Andalusian parliamentary election was held on Sunday, 9 March 2008, to elect the 8th Parliament of Andalusia, the regional legislature of the Spanish autonomous community of Andalusia. All 109 seats in the Parliament were up for election. The election was held simultaneously with the 2008 general election.
Incumbent President Manuel Chaves from the Spanish Socialist Workers' Party (PSOE–A) was re-elected for a sixth term in office with a slightly reduced majority. Final results showed a major breakthrough by the People's Party (PP), which gained 10 seats from 37 to 47 and scored its best result in the community at the time. United Left (IULV–CA) remained stagnant with 6 seasts, whereas the Andalusian Party (PA) suffered a major drop in support and failed to enter the regional parliament for the first time.
The Parliament of Andalusia was the unicameral legislature of Andalusia at the time of the 2008 election. Legislative initiative for those areas of responsibility attributed to the regional government belonged to this chamber, which also had the attribution of granting or revoking confidence from the President of Andalusia.
The President had the ability to dissolve the chamber at any given time and call a snap election. Additionally, the Parliament's dissolution was automatically triggered if investiture attempts failed to elect a regional President within a two month-period from the first ballot.
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 1% of registered electors in a particular district in order to be able to field candidates.
All 109 Parliament seats were allocated to eight multi-member district—each constituency corresponding to a province—using the D'Hondt method and a closed list proportional representation. Each district was entitled to an initial minimum of eight seats, with the remaining 45 seats allocated among the eight provinces in proportion to their populations on the condition that the number of seats in each district did not exceed two times those of any other. A threshold of 3% of valid votes—which included blank ballots—was applied, with parties not reaching the threshold not entitled to enter the seat distribution.
With the Spanish Socialist Workers' Party (PSOE) regaining its absolute majority in Andalusia in the 2004 election, Manuel Chaves was able to govern alone again, after 10 years of minority government, having relied on the support of the Andalusian Party in the previous 8 years. Teófila Martínez, who had been PP candidate for President of Andalusia in the previous two elections (1996 and 2000), was replaced by Javier Arenas as head of the Andalusian People's Party (PP). Arenas had been PP candidate in the 1994 and 1996 elections, but left the PP regional leadership in order to become Spain's Minister of Labor and Social Affairs in the Aznar cabinet and, later, Secretary-General of the People's Party.
Concurrently in 2004, José Luis Rodríguez Zapatero from PSOE was elected as Spain's new Prime Minister, after unexpectedly winning the 2004 general election. This meant that, for the first time since 1996, both the regional and national governments were ruled by the same party.
The province of Almeria, due to a growth in population over both the total of Andalusia and the previous elections in 2004, won a seat for a total of 12 to the loss of Cordoba, which also remained at 12.
