Religious tourism plays an important role in Iranian cultural and economic sustainability. Due to the special nature of the Iranian political establishment, this type of tourism provides many potentials for tourism development in different parts of Iran. Making the best use of these capacities requires recognition of the barriers and challenges lying ahead of the development of religious tourism. Therefore, this study set out to identify the challenges facing religious tourism, using thematic analysis (TA) and interpretive structural modeling (ISM). Moreover, the relationship model between the influential factors involved in this regard was extracted at three levels via the thematic network. Finally, MICMAC analysis was conducted to measure the influence power and dependence of the factors. The required data were collected through library research and administering a questionnaire on 15 experts familiar with the subject matter who were selected through purposive sampling, out of whom 11 experts completed the questionnaire. The findings of the study indicated that variables such as lack of attention to the chain of providing religious tourism services, lack of programming, policymaking, and monitoring the religious tourism process, and not allocating budget and financial supports for religious tourism development in Iran played essential and key roles in the non-development of this type of tourism. These variables were placed at the third level of the model that affect the second level variables. It was also found that the variables such as inefficient management of religious tourism facilities and services, inefficient management of religious attractions and events, and improper management of religious tourism marketing were dependent variables that were placed at the first level of the model.
