Introduction: With the success of Masoud Pezeshkian as the 9th President of Islamic Republic of Iran and the importance of recognizing the possible foreign policy changes in the upcoming four-year period (1403-1407), the main question of this paper is what will be the most important paths of the foreign policy change in this Period? In answer to this question, based on the “synthetic model of foreign policy change”, the hypothesis of this research is that there are three general paths for Iran's foreign policy change in the 14th administration (new alternative inputs from domestic or international sources, finding pre-existing inputs into the foreign policy decision-making apparatus and finally changes in narrative by foreign policy decision-makers. So, the main aim of this research is a theoretical aim, focusing on the paths of in Iran's foreign policy change during the 14th administration.Methods: This research is explanatory research in which the data analysis will be through the adaptation of the proposed conceptual model with the case study. The conceptual framework of this research is focusing on the concept of " foreign policy change" and the theoretical models and literature about it. Research data have also been collected through virtual sources (English articles) and documents.Results and Discussion: The research findings and the main argument of the proposed model of this research is that the foreign policy change can take place through any of the three paths. There are influencing variables under each of these paths. These variables, which include material and semantic variables and are located at domestic and international levels, determine the paths of change. For example, windows of opportunity, external shocks and events and new environmental pressures (incentives and punishments) are three important international and material factors in the form of independent variables and as new inputs. If these variables are understood by the mental framework of new foreign policy decision makers (mediating variable), they can cause changes in Iran's foreign policy (dependent variable). On the other hand, the different understanding of the new decision-makers in the 14th administration as the intellectual and cognitive influencing factors (independent variable and as new inputs) is important in creating different outputs of foreign policy (dependent variable). The second path examines the already existing alternative inputs to the decision-making apparatus of the 14th administration. If these inputs are not interpreted differently by new decision makers (intermediary variable), they can cause continuity or minor changes in foreign policy. The third path is through the manipulation of certain elements within the main narrative that the Iranian defines for themselves, by foreign policy decision makers, which makes the policy change legitimate and possible for the audience.Conclusion: The first conclusion of the research is that for the accurate analysis of the possible paths of change in foreign policy of 14th administration, it is necessary to consider the elements of three paths simultaneously. On the other hand, any of these paths of change can lead to changes in the goals/tools or both in the direction of Iran's foreign policy. The extent of change can include radical change or minor changes in one or more specific areas.
