The opposition People's Party (PP) secured its best result in a regional election up to that point, whereas United Left/The Greens–Assembly for Andalusia (IULV–CA) saw a major decrease in both votes and seats.

[1] Voting for the Parliament was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Andalusia and in full enjoyment of their political rights.

The 109 members of the Parliament of Andalusia were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which included blank ballots—being applied in each constituency.

[1][2][4][5][6] In smaller constituencies, the president had the prerogative to dissolve the Parliament of Andalusia and call a snap election, provided that no motion of no confidence was in process and that dissolution did not occur before one year had elapsed since the previous one.

The highest percentage figure in each polling survey is displayed with its background shaded in the leading party's colour.
