Narcissism is a phenomenon that can have serious consequences for organizations and their employees. On the other hand, employees who show organizational citizenship behaviors, such as helping their colleagues, can help create a positive and productive work environment. In this study, it was aimed to determine teachers' perception levels of organizational narcissism and citizenship, the relationship between narcissism and citizenship, and the effect of narcissism on citizenship. The research was conducted on 400 teachers. Data were collected using the Organizational Narcissism Scale and Organizational Citizenship Scale. As a result of the research, it was determined that teachers' perceptions of organizational narcissism and organizational citizenship were at a moderate level. However, there are significant positive relationships between organizational narcissism and organizational citizenship. In addition, organizational narcissism was found to be a significant predictor of organizational citizenship. In the light of the results obtained from the research, suggestions for researchers and future research are given.
