Iran’s foreign policy toward international organizations has always oscillated between divergence and convergence, depending on the status of the country in question and the statesmen's point of the view. This study aimed to examine the status of international organizations in Iran’s foreign policy. A divergent approach to international organizations was adopted during 1981-1988 and 2005-2013. This believe in a domination system in the world, and try to change the status quo and the fundamental rules of the international system. One could argue that the domination of this approach in Iran’s foreign policy undermined the national interests and security. On the other hand, since 1979, it has been revealed that whenever Iran has had a convergent interaction with international organizations (i.e., 1979-1980 and 1988-2005); it has helped Iran's national interest and security. Furthermore, cooperation with international organizations in various fields has provided opportunities for political, economic and cultural ties of Iran.
