The aim of this study was to present the organizational identity model for Iranian Premier League football clubs. The research method employed was qualitative, utilizing a phenomenological approach. The participants in this study consisted of sports club managers and owners, as well as university professors specialized in sports management and sports sociology. Purposeful sampling was employed, and 19 interviews were conducted based on theoretical saturation. The data collection tool was semi-structured interviews, and credibility and reliability of the results were assessed using strategies such as believability, transferability, confirmability, and dependability. The data analysis involved three coding stages: open coding, selective coding, and theoretical coding. Through the coding of the conducted interviews, the initial coding resulted in 83 codes, selective coding identified 21 concepts, and theoretical coding revealed 10 themes, namely social responsibility, club legitimacy, fan loyalty, club image, external stakeholder pressure, culture, internal stakeholder pressure, brand identity, club development, and capabilities. The core theme, "external image of the club," emerged from the conceptual relationship between the initial codes, concepts, and themes. This core theme forms the basis of the theory, indicating that the organizational identity of football clubs refers to external perceptions of the clubs, with factors such as social responsibility, club image, external stakeholder pressure, culture, internal stakeholder pressure, and brand identity playing significant roles in its formation. Furthermore, the organizational identity of football clubs, as an external perception, leads to fan loyalty, club legitimacy, and club development.
