Satisfaction with Iranian national identity includes a person's attitude and his general evaluation towards his identity as a whole or some aspects of his life. In this research, the relationship between self-differentiation, ethnic hegemony and satisfaction with national identity was investigated. The aim is to determine the relationship between self-differentiation and the mediating role of ethnic hegemony on satisfaction with the national identity of Iranian ethnicities. The present research is a descriptive-applicative and correlational survey, the statistical population of which consists of men and women from five ethnicities: Persian, Arab, Baloch, Kurdish and Azeri. The sample size of this research includes 645 people in the young age group(15-30) who were selected based on Cochran's formula. In this research, proportional stratified sampling was done. The most important criterion for entering the research was the ethnicity of the people. The data was collected based on Skorn and Friedland's own differentiation questionnaire and researcher-made questionnaire. The findings of the research regarding the three hypotheses proposed in this research indicate the confirmation of all three hypotheses. The results show that self-differentiation is effective on ethnic hegemony and ethnic hegemony is also effective on satisfaction with Iranian national identity. Manuscript profile
