In recent years, "City" as the main human settlement has become more important than ever. Cities, as the engine of growth and the main focus of increasing development challenges in environmental, socio-economic, political-institutional, spatial-critical, etc. dimensions, have found complex and diverse aspects and have turned the study of the city into a complex and interdisciplinary field. Iran is also a country that has begun, accelerated, and completed its rapid urbanization process after the second half of the twentieth century. However, the expansion of systematic urban studies on the subject of the city and its vital dimensions has been delayed. The aim of the present article is to systematically review published research with internationally valid indexes. For this purpose, all articles related to the subject of "Iranian cities" in the Scopus scientific database from 1964 to 2026 were analyzed. To extract and visualize the findings, Bibliometrix library tools in the Rstudio and VOSviewer programming environments were used, which can provide more appropriate findings. The results of the study show that in recent years, the volume of research on Iranian cities has expanded significantly. Accordingly, researchers active in the specialized fields of environmental health, geology, and epidemiology have played a prominent role in publishing their research in internationally indexed journals. However, the role of disciplines that specialize in studying cities (such as urban development, urban planning, urban management, architecture, etc.) has been less prominent. In addition, the co-occurrence analysis of keywords in the subsystems of natural-ecological, social-health, political-management, and physical-spatial issues shows that the published articles mainly reflect the urban issues and challenges of Iran and have less expressed innovations and innovative solutions to solve the problems.
