The shift to the private sector, or what we call privatization, is one of the most prominent changes that have taken place in the economies of the developed and developing world during the last two decades, it gained its importance after the Conservative government in Britain led by Prime Minister Margaret Thatcher carried out its comprehensive program to transfer public sector projects and activities to the private sector since 1979, with success. Comprehensive transformation experience programs for transferring public projects and activities to the private sector in various countries have been completed. In light of the government\\'s orientation towards a market economy as an economic system instead of the central economy, and the state adopts economic concepts that allow the private sector to manage many public and state-owned projects, there is a trend to try to apply the concept of privatization in sports activity for its economic, social, political and media return, as well as reducing financial support Provided to sports clubs and the lack of it in recent years, these clubs resort to searching for new sources of financing without relying on government support to cover the costs of the activities provided. This research aims to privatize sports clubs by identifying: Methods and methods of privatization Sports clubs Problems facing the application of privatization in sports clubs The research community of businessmen working in the field of sports and within the lists registered with the Ministry of Youth and Sports for the latest update 2017, totaling 93 individuals.
