This study aims to examine whether there is a connection between populist parties and voter turnout in the European parliament election 2019. Populist Parties have had remarkable high success in recent years, which makes it interesting to study the electoral effects of this. Based on the theoretical framework by Stoke’s, Reif and Schmitt and previous literature on populism and voter turnout, this study analyzes the possible connection between populism and voter turnout. The main question is therefore if there is a connection between populist parties and voter turnout and as a second question if there are any differences between rightwing populists and the leftwing populists. According to the previously existing literature, there are three hypotheses, one that the populist parties will have a higher voter turnout than the mainstream parties due to their ability to mobilize people, the second hypothesis is that the voter turnout will be lower for populist parties since most of them are Eurosceptic and the third hypothesis is that the right wing populist will have a higher voter turnout than the left wing populists.  Through a quantitative analysis based on a dataset from Leibniz Institute for Social Sciences, the study aims to find a connection between type of party, populist party or mainstream party, and voter turnout. The result in the regression analysis indicates that the populist parties present a slightly higher voter turnout than the mainstream parties with the context of the country included. However, since this result is not significant, one cannot be sure if this potential connection is random or causal. Further studies need to investigate this to determine if a relationship exists.
