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 counties of Croatia are the first-level administrative subdivisions of the Republic of Croatia. Since they were re-established in 1992, Croatia has been divided into 20 counties and the capital city of Zagreb, which has the authority and legal status of both a county and a city. As of 2015, the counties are subdivided into 128 cities and 428 municipalities. The divisions have changed over time since the medieval Croatian state. They reflected territorial losses and expansions; changes in the political status of Dalmatia, Dubrovnik and Istria; and political circumstances, including the personal union and subsequent development of relations between the Kingdom of Croatia-Slavonia and the Kingdom of Hungary.
