Opinion polling for the 2019 Finnish parliamentary election
# Opinion polling for the 2019 Finnish parliamentary election

In the run up to the 2019 parliamentary elections in Finland, various organizations carry out opinion polling to gauge voting intention in Finland. Results of such polls are displayed in this article.

The date range for these opinion polls are from the previous parliamentary election, held on 19 April 2015, to the present day.

## Poll results

Poll results are listed in the table below in reverse chronological order, showing the most recent first. The highest percentage figure in each poll 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. The table uses the date the survey's fieldwork was done, as opposed to the date of publication. However, if that date is unknown, the date of publication will be given instead.

The Sipilä Cabinet is composed of the top three parties from the previous election: Centre (Kesk), National Coalition (Kok) and Finns (PS) parties. But after the split of the Finns Party, Blue Reform (Sin) took the party's place in the Sipilä Cabinet.
