Regular elections in Croatia are mandated by the Constitution and legislation enacted by Parliament. The presidency, Parliament, county prefects and assemblies, city and town mayors, and city and municipal councils are all elective offices. Since 1990, seven presidential elections have been held. During the same period, ten parliamentary elections were also held. In addition, there were nine nationwide local elections. Croatia has also held three elections to elect members of the European Parliament following its accession to the EU on 1 July 2013.

The Croatian Parliament or the Sabor is the unicameral legislature of Croatia. Under the terms of the Croatian Constitution, the Sabor represents the people and is vested with legislative power. The Sabor is composed of 151 members elected to a four-year term on the basis of direct, universal and equal suffrage by secret ballot. Seats are allocated according to the Croatian Parliament electoral districts: 140 members of the parliament are elected in multi-seat constituencies. An additional three seats are reserved for the diaspora and Croats in Bosnia and Herzegovina, while national minorities have eight places reserved in parliament. The Sabor is presided over by a Speaker, who is assisted by at least one deputy speaker.
