# Opinion polling for the 2021 Norwegian parliamentary election

In the run up to the 2021 Norwegian parliamentary election, various organisations carried out opinion polling to gauge voting intention in Norway. Results of such polls are displayed in this article.
The date range for these opinion polls are from the previous general election, held on 11 September 2017, to 13 September 2021, the day of the election. Unlike most nations, Norway's constitution does not allow early elections before the four-year term limit.
