The aim of the present study is to investigate the modeling of the effect of self-leadership and strategic thinking on organizational setup with the mediating role of adaptability and individual-organization fit. The method is applied in terms of its purpose, quantitative in terms of its implementation method, and causal in terms of its research-survey nature. The statistical population of the study includes 216 employees of the General Directorate of Sports and Youth Organization, of which 139 were calculated as a statistical sample of Cochrane performance and selected randomly by stratified sampling. To collect data, standard questionnaires of self-leadership (Neck and Houghton, 2006), strategic thinking (Lydka, 1998), organizational fit (Elzabek, 1994), adaptability (Denison, 1996), and individual-organization fit (Scroggins), 20. Structural solutions model and partial least squares methods (PLS3) were used to analyze the data. The result showed that self-leadership, with the mediating role of adaptability and individual-organization fit, has a significant effect on organizational initiation. Also, strategic thinking, with the mediating role of adaptability and individual-organization fit, has a significant effect on organizational legitimacy. As a result of the research results, it can be concluded that investing in the development of self-leadership skills and improving the power of strategic thinking can provide the basis for improving adaptability and improving the level of individual fit with the organization, and in this way, significantly increasing legitimacy among employees and stakeholders. This can lead to strengthening internal cohesion, increasing organizational trust, and improving the status of the organization both internally and externally.
