In the run up to the next Slovenian parliamentary election, various organisations carry out opinion polling to gauge voting intention in Slovenia. Results of such polls are displayed in this article.
The date range for these opinion polls are from the previous general election, held on 13 July 2014, to the present day. The next parliamentary election is scheduled to be held no later than 28 July 2018.
Poll results are listed in the tables below in reverse chronological order, showing the most recent first. The highest figure in each survey is displayed in bold, and the background shaded in the leading party's colour. In the instance that there is a tie, then no figure is shaded. There are, principally, four polling organizations that conduct election polling on a regular basis within Slovenia. The results are generally published on a monthly basis. Episcenter (results published by Planet SiOL.net and Planet TV), Mediana (results published by the Slovenian television channel POP TV and their respective multimedia web portal 24ur.com) and Ninamedia (results variably published by either POP TV, national public broadcasting organization RTVSLO and the Slovenian daily newspaper Dnevnik) are independent opinion research firms, whereas Delo Stik is the in-house opinion polling organization of the Slovenian daily newspaper Delo. Parsifal SC conducts opinion polling for the recently founded conservative media conglomerate, Nova24TV, however, the company is (like the news agency itself) closely tied to the largest Slovenian conservative party, SDS.
