The 2003 Upper Austrian state election was held on 28 September 2003 to elect the members of the Landtag of Upper Austria. The governing Austrian People's Party (ÖVP) remained the largest party in the face of a strong performance from the Social Democratic Party of Austria (SPÖ). The Freedom Party of Austria (FPÖ), which had won over 20% in the previous election, lost more than half its vote share and fell to 8%; most of this flowed to the SPÖ. The FPÖ also lost both its state councillors. The Greens became the third largest party and won their first state councillor in Upper Austria. As the ÖVP and SPÖ won four each, the Greens held balance of power in the state government.
