Opinion polling for the next Slovenian parliamentary election

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 parliamentary election, held on 3 June 2018, to the present day. The next parliamentary election is scheduled to be held no later than four years since the previous one.

Poll results.
Poll results are listed in the table 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 case of a tie, no figure is shaded. When available, seat projections for 88 out of 90 seats (without seats reserved for minorities) are displayed below the percentages in a smaller font. 46 seats are required for an absolute majority in the National Assembly.

In late February 2021, falsified results from a 24ur Mediana poll were published and began to circulate on Twitter. The falsified image purported to show the tabulated results of a spiked poll that found pro-government parties in a comfortable lead. The falsified results were then shared by multiple politicians (including the prime minister). 24ur lodged a criminal complaint against the originator of the fabricated poll.
