This paper aims to survey the challenges which the conception of national identity has encountered in the age of globalization, and how they affect Iranian national identity. In addition, we seek a proposal to take some precautionary measures to maintain the national identity. Generally, national identity is considered as awareness, belonging and loyalty which members of a society feel about their national communities and constituents. By weakening the national states` traditional function of identity-forming, and provoking the formation of supra-national and bricolage identities, and strengthening sub-national identities, globalization as a worldwide integrated process having affected all dimensions of human society and it has underpinned a large number of people`s feeling of belonging and loyalty to their national identity and it plays an important role in the rise of crisis in the national identity of many countries. Widespread communication technologies, especially the Internet, play an important role in this process. Iran has also been impressed by process of globalization so the Iranian national identity has been challenged too. Nonetheless, the present paper believes that the government of Islamic Republic of Iran might prevent the occurrence of crises in this scope and maintain the national identity through understanding the globalization process properly and making effective policies and precautionary measures.
