This study investigates the link between perceived discrimination and political trust among immigrants in European countries. Focusing on perceived discrimination, I emphasize the diversity of mechanisms through which discrimination is perceived by immigrants; in other words, perceptions of discrimination are multidimensional. This is in stark contrast to most of the research that uncritically assumes that the perceptions of discrimination are unidimensional. Employing the European Social Survey, I find that each of the diverse dimensions of perceived discrimination has different associations with immigrants’ political trust. Furthermore, the association between diverse dimensions of perceived discrimination and political trust varies depending on the immigrant’s generational status. For first-generation immigrants, their trust in political institutions is related to seven types of perception of discrimination, whereas, for the second generation, it is linked only to four types. This indicates that first-generation immigrants’ political trust is more responsive to the perceptions of discrimination in comparison to the second generation of immigrants.
