Today, tourism is recognized as the world's largest and most diverse industry. Despite their significant potential in attracting tourists, Islamic countries have not been that successful in this area. The main question raised in the present study is that: what are the barriers to attracting tourists in these countries? The research was carried out by a library method, and the results showed six categories of barriers to tourism in Islamic countries, including: 1) structural, 2) cultural and religious, 3) economic, 4) human, 5) legal, and 6) political and international barriers.
