Todays, cities have become one of the mos t complicated sys tems, which may become fragile when not managed appropriately. In order to prevent fragility, cities should respond more quickly and effectively to complicated threats, which requires an accurate unders tanding of the concept of fragility. In this regard, a sys tematic review was conducted based on Preferred Reporting Items for Sys tematic Reviews and Meta-Analyses (PRISMA) to unders tand the concept of urban fragility by electronic search using keywords combined with Boolean OR and AND operators in Google Scholar, ISI Web of Science, and Scopus. Based on the reviewed articles, the dimensions of urban fragility, including the economic, social, governmental, environmental, international relations, and economic, social, and political conditions of individuals, were identified for each component and indicator. Given the definition of fragility and its dimensions, the present s tudy can provide an opportunity for identifying the causes of fragility in cities and providing some solutions.
