The main objective of this research was to investigate the relationship between knowledge management and entrepreneurship among the managers of German football sports clubs. The present study is quantitative, applied research in nature, and descriptive-correlational in method. The statistical population of the study consisted of all managers of German football sports clubs, among which 214 managers were selected as the research sample using the cluster sampling method. To collect data, two questionnaires were used, namely the Lawson's Knowledge Management questionnaire and the Scarborough and Zimmer Entrepreneurship Scale. Descriptive statistics including mean and standard deviation and inferential statistics including Pearson correlation, regression analysis, independent t-test, and one-way analysis of variance were used to analyze the data using SPSS software. The results indicated a positive and significant relationship between knowledge management and entrepreneurship among private sports club managers (r=0.79). Furthermore, there was a significant relationship between the components of knowledge management (creation, sharing, and application of knowledge) and entrepreneurship, and among these three components, the application of knowledge had the highest correlation with entrepreneurship.
