In the run up to the 2019 Portuguese legislative election, various organisations 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 previous legislative election, held on 4 October 2015, to the present day.

Graphical summary[edit]

Graph showing a 30-day average trendline of Portuguese opinion polls from the election in 2015 to the election in 2019. Each line corresponds to a political party.

Party vote[edit]

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, then no figure is shaded but both are displayed in bold. 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.
