In this study, the impact of youth identity crisis is investigated on the national security of the Islamic Republic of Iran. The research method is qualitative; the library method is used for data collection; and data analysis is carried out with descriptive-analytical method. The main research question is how does the identity crisis in youth affect the national security of the Islamic Republic of Iran? For this question, the hypothesis was that the identity crisis in young people would undermine national security by undermining indigenous values ​​and beliefs as the most important components of identity. The findings of the study indicate that the identity crisis in young people is manifested through the lack of social security for them, the duality, and indecision in the fundamental values ​​of the ruling system in the form of asociality, social alienation, mass uprisings and social anomalies, and it has threatened Iran's national security.
