Iran's PHC system faces challenges that limit its effectiveness and efficiency. The aim of this study was to identify strategies to strengthen Iran's PHC system. Materials and Methods: A realistic review method was used in this research. Published articles on strategies to strengthen the PHC system between 1978 and 2019 were searched in eight databases and Google scholar search engine. Finally, 29 articles were found to be eligible for inclusion in this study; framework analysis was done using the MAXQDA-10 software.  Results: Twenty-nine strategies were identified for strengthening the PHC system. A well designed PHC system is one with the following characteristics: realistic goals and appropriate strategies  equipped with necessary resources, organized in multidisciplinary teams that provide comprehensive and quality health services (intervention program), with strong governance and leadership, financing, work force, equipment and medicines, information systems and robust health services delivery processes and well adpated to the external environment (context). Such a PHC system will increase healthcare providers’ satisfaction and commitment, as well as the  patients’ trust, participation and satisfaction (the mechanism) and, finally, promotes, restores, and maintains the people health (result). Conclusion: A strong PHC system is a pre-requisite for strengthening a health system. Various strategies such as strengthening management and leadership, improving organizational structure and culture, improving the information system, empowering human resources and increasing population coverage can lead to an improved PHC system. Historical, social, cultural and economic factors affecting the health system should be considered in redesigning and stregtening a PHC system.
