In the run up to the 2019 Spanish local elections, various organizations carried out opinion polling to gauge voting intention in local entities in Spain. The results of such polls for municipalities in the Community of Madrid are displayed in this article. The date range for these opinion polls is from the previous local elections, held on 24 May 2015, to the day the next elections were held, on 26 May 2019.
