The 2005 Styrian state election was held on 2 October 2005 to elect the members of the Landtag of Styria. The result was a historic defeat for the Austrian People's Party (ÖVP), who had governed the state uninterrupted since 1945. The Social Democratic Party of Austria (SPÖ) became the largest party on a swing of over nine percentage points. The election was also significant in other ways: the Freedom Party of Austria (FPÖ) lost all its seats for the first time since entering the Landtag in 1949, and suffered its worst result since 1974 in terms of vote share. Conversely, the Communist Party of Austria (KPÖ) returned to the Landtag after a 35-year absence. It became the third largest party with four seats.
