The European Parliament election of 2004 took place on 12–13 June 2004.
The Olive Tree was the most voted list in Sicily with 28.6%, followed by Forza Italia (21.5%), National Alliance (14.5%) and the Union of Christian and Centre Democrats (14.0%).
Raffaele Lombardo, who was elected to the European Parliament for the Christian Democrats, left that party in 2005 to launch the Movement for Autonomy, which would have become a stable political force in the region.
