Abstract: USR has become the axis for improving sustainable educational future depending on the students, who represent the core center of Society, Universities and Business future. Thus, many Lebanese universities have established CSR departments and set out socially responsible strategies to involve their students in social activities and programs to improve the CSR concept and social awareness. On the other side, Sustainable leadership has spread in various departments, especially in the educational field. Hence, in this study, I will try to visualize the correlation between sustainable leadership factors (traits, knowledge, styles and actions) on the USR dimensions (social, ethical, educational, environmental) in the Lebanese public and private universities. Basically, it is hypothesized that Sustainable leadership factors have a positive effect on the Social Responsibility of the Lebanese Universities. For assessing this relationship, I had conducted an online survey with a total sample of 600 Lebanese professors, out of which 404 completed questionnaires were obtained. I used the Confirmatory Factor Analysis (CFA) and the hypotheses are tested by using structural equation modeling SEM, to test the reliability and validity. The results show the difference in the application of Sustainable leadership practices between public and private universities where the sustainable leadership traits have a positive impact on University social responsibility in both public and private universities, moreover, the sustainable leadership styles show negative impact on University social responsibility in both public and private universities, where the leadership actions show the positive correlation in the Lebanese private universities and negative impact in the Lebanese public university.
