Increasing the ability to access large volumes of information and the speed of their transmission to audiences around the world has challenged foreign policy management by governments. In such a situation, one of the drivers of diplomacy, is the tourism. A country that attracts foreign tourists, in addition to economic benefit, can take steps to spread its culture to other countries and thus display its cultural authority. Iran can also use this capability to present the true face of Iran, which has been introduced insecure after the Islamic Revolution, through the use of vast tourism capacity through cultural diplomacy to the world. The question is, what is the role of tourism in the cultural integration of the Islamic Republic of Iran in the international arena? The purpose of this study is to examine the role of tourism in cultural diplomacy by using a descriptive-analytical approach and interviewing relevant authorities. In this research, using descriptive-analytical method and interviewing relevant authorities, we have tried to examine the role of tourism in cultural diplomacy. The research findings support the hypothesis that; tourism has a great influence on promoting cultural diplomacy and deepening relations between states and nations, and this has been particularly considered by decision makers in the last decade, and has paid serious attention to macro policies, but this requires strict policy and government support from the private sector in the field of tourism. But the most important problems are in the foreign arena; Including Iranophobia, sanctions and colonialism.
