The present study is applied in terms of aim, descriptive correlation in terms of nature, and survey in terms of method. The statistical population of the present study included officials of Iran’s sports federations, Premier League sports clubs, as well as club sponsors (300 people). Based on Morgan's table, the sample size was estimated at 169 people who were selected by a convenience random sampling method. To collect data, after reviewing the research literature and surveying experts, a researcher-made questionnaire consisting of 52 questions in 7 dimensions was developed in the form of a five-point Likert scale from strongly agree to strongly disagree, which its face and content validities were confirmed. Cronbach's alpha and Guttmann coefficients were obtained above 0.7, confirming the reliability of the research tool. Results revealed that the model of factors affecting the attraction and retention of sponsors in the sports sector of Iran has a favorable fit. In this model, the factors related to attracting sponsors include club factors, environmental factors, and league and event factors.
