This thesis explores the role of football clubs in promoting Corporate Social Responsibility (CSR), with a particular focus on analyzing practices in the Republic of Croatia. The research centers on how football clubs, as significant social entities, can contribute to sustainable development by adapting their business strategies.   The theoretical framework of the study elucidates the fundamental dimensions of CSR, including its historical development, key aspects, impact on stakeholders, and examples of best practices in both Croatia and globally. Survey methods were employed in the research component of the thesis, supplemented by the theoretical analysis, to gain insights into current practices. The results reveal variations in the implementation of CSR and underscore the need for further development and adaptation of business strategies. However, they also indicate that the strategic guidelines for CSR are largely aligned, particularly in key considerations such as the importance of CSR policies within organizational structures and the implementation of critical social and societal principles, including zero tolerance for bullying and discriminatory behavior, as well as the promotion of equality, diversity, and significance. Furthermore, the survey results highlighted that the primary barriers to more robust CSR policy implementation, which require continuous attention, lie within national legislation and the limited integration of CSR policies within the sports sector, alongside the relatively weak understanding of comprehensive practical implementation. The execution of strategic CSR guidelines demands considerable time, financial resources, and human capital. The thesis concludes that, while there are positive examples, there is also significant room for improvement, particularly in terms of better alignment with European and global standards.
