Opinion polling for the next Portuguese legislative election
From Wikipedia, the free encyclopedia
In the run up to the next Portuguese legislative election, various organisations will carry out opinion polling to gauge voting intention in Portugal. Results of such polls are displayed in this article. The date range for these opinion polls are from the 2025 Portuguese legislative election, held on 18 May, to the present day.
Nationwide polling
Graphical summary
Polling
Poll results are listed in the table below in reverse chronological order, showing the most recent first. The highest percentage figure in each polling survey is displayed in bold, and the background shaded in the leading party's colour. In the instance that there is a tie, parties are shaded with their colour. The lead column on the right shows the percentage-point difference between the two parties with the highest figures. Poll results use the date the survey's fieldwork was done, as opposed to the date of publication.
Polls that show their results without distributing those respondents who are undecided or said they would abstain from voting, are re-calculated by removing these numbers from the totals through a simple rule of three, in order to obtain results comparable to other polls and the official election results.
