Justice, as one of the main goals of urban planning, does not simply include the distribution of tools, benefits, harms, or services, but its scope is as wide as all dimensions of the city and plays a very effective role in the lives of citizens. However, given the importance of identifying the most important criteria for the manifestation of the virtue of justice in the dimensions of the city and, consequently, the strategies for promoting justice in Iranian cities, no study has been conducted on this subject so far. For this purpose, this research was conducted with the aim of identifying the most key criteria and strategies for the manifestation of the virtue of justice in the urban environment. The research method in this research was a combination of quantitative and qualitative methods, and library studies, expert consensus, and interviews were used to collect data, and content analysis and structural analysis methods were used to analyze them. The findings of this research show that the criteria of equal opportunities and class equality, difference and diversity and freedom, need, entitlement, participation in the public interest, and fair distribution of facilities, space, population, and resources, participation, etc. have had the most repetition in domestic studies, respectively. Also, the criteria of diversity, public benefit, equality, inclusiveness, participation, access, need and entitlement are the most key criteria in this area, respectively. As a result, a just city is a city in which the criteria of diversity, public benefit, equality, inclusiveness, participation, access and need are manifested in all physical dimensions, use and activity, social, economic, cultural, political, environmental, transportation and housing, and entitlement is manifested solely in its economic dimension.
