The main purpose of this study was to determine the effect of entrepreneurial orientations on financial performance among private sports clubs. In this correlational study (structural equation modeling), 224 private sports clubs were selected out of the 513 sports clubs in Tehran city using the relative stratified random sampling method, and their managers completed individual information and entrepreneurial orientation scale forms. The data were analyzed using the Pearson correlation coefficient and structural equation modeling at a 95% confidence level. The results showed that the levels of entrepreneurial orientations of private sports clubs in Tehran in the dimensions of innovation, PROACTIVENESS, and competitive aggressiveness were higher than the average level, and in the dimensions of risk-taking and autonomy, they were at a moderate level. Based on the correlational analysis, the financial performance of a private sports club had significant and positive relationships with the overall level of entrepreneurial orientation and its dimensions, in which the strongest and weakest correlations were related to innovativeness and risk-taking, respectively. Structural equations modeling showed that the entrepreneurial orientations of innovativeness, PROACTIVENESS, competitive aggressiveness, autonomy, and risk-taking had the highest share in explaining a club’ s financial performance, respectively, and overall, explained 58% of its variance. Based on the findings, entrepreneurial orientations, especially innovativeness and PROACTIVENESS, can enhance the financial performance of a private sports club.
