The aim of this study is to present a model for sustainable financial resource provision in Iranian sports federations. This research was conducted qualitatively using the grounded theory approach. The statistical population consisted of 17 experts in the field of sports management and the management of sports federations. A semi‑structured interview was used as the data collection tool. Grounded theory was employed for collecting and analyzing the data. Data analysis was carried out in three stages: open coding, axial coding, and selective coding. MAXQDA 24 software was used for data analysis.The findings indicated that sustainable financial resource provision in Iranian sports federations, as the core phenomenon, is influenced by factors such as dependency on government budgets, lack of stable financial resources, and pressure from regional and global competitions, all of which emerge within a context shaped by economic constraints, managerial weaknesses, and infrastructural challenges. Factors such as government policies, the role of media, and organizational capabilities moderate the intensity and direction of these efforts. To overcome these challenges, strategies such as diversifying financial resources, commercializing sports, and strengthening federation branding are essential. Successful implementation of these strategies leads to outcomes such as financial independence, infrastructure development, and enhanced competitiveness of sports federations, ultimately ensuring the sustainable growth of sports in the country.
