Koper (), officially known as the 9th constituency (), is a special constituency (electoral unit) of the National Assembly, the national legislature of Slovenia, to elect a member of the Italian national community. The constituency was established in 1992 following Slovenia's independence from Yugoslavia. It consists of the municipalities of Izola, Koper and Piran. The constituency currently elects one of the 90 members of the National Assembly using a single round majority electoral system. At the 2026 parliamentary election the constituency had 2,822 registered electors.
History The 9th constituency (Koper) was one of the ten constituencies established by the Determination of Constituencies for the Election of Deputies to the National Assembly Act (ZDVEDZ) () passed by the Assembly of the Republic of Slovenia () in September 1992. It consisted of the municipalities of Izola, Koper and Piran.
Electoral system Koper currently elects one of the 90 members of the National Assembly using a single round majority electoral system. Prior to 2021, the Borda count ranked voting was used with voters ranking candidates in order of preference. These preferences were converted to points - each first preference received as many points as there were candidates, each second preference received one fewer point etc. The candidate with the most points was elected.
In addition to voting for an Italian candidate, electors belonging to the Italian national community in Koper may also vote for a candidate from the national parties in their electoral district. This means they have two votes, violating the principle of equal voting.
