Signs of the collapse of the monopolar system have been revealed. The most important manifestation of the collapse of the unipolar system that dominated the world over a decade after the Cold War could be seen in the "emergence" of the Brix group. Hence, the order in which emerging powers play an effective role are taking shape, in a way that many thinkers speak of a multipolar system. In the same vein, the BRICS Group is the most powerful emerging power in the international multipolar system, given its massive population and growing economic power. Given the current state of the international system, this paper seeks to answer the question, what is the most important factor affecting Iran's decision on possible membership in the BRICS and what is the purpose of Iran in membership in this group? The descriptive-analytic method and the data collection tool are also libraries. The most important findings of the research indicate that Iran is influenced by the conditions created in the structure of the international system (weakening the global US hegemony and creating a structural opportunity) by adopting a policy appropriate to membership in this group seeking to cope with hegemony Americanism is global in the world and, as a result, is a guarantee of national security, and the concept of hegemony and structural theories can better explain this behavior. In addition, membership in BRICS may provide areas for increasing regional power in West Asia.
