Ensuring that tourists leave the destination with a positive image in their mind and as satisfied is an important factor for achieving competitive advantage. One of the satisfaction of this is the services of the tourist guides accompanying the tourists during their visit to the destination. The aim of this study is to determine the impact of the performance of tourist guides on destination image and the moderating role of ethical behaviors in this relationship. The data of this study, which was designed as a quantitative research, was obtained by using the questionnaire technique applied to 438 domestic and foreign tourists visiting Nevsehir province. In the results of the study, it was concluded that the performance of the tourist guide had an effect on destination image. At the same time, it was concluded that the "honesty" and "reliability" dimensions of the ethical behavior of the tourist guides had a moderating role in this relationship, while the dimensions of "professional responsibility" and "fairness" did not have a moderating role. Finally, based on the findings, some suggestions have been made to the tourist guides and the educational institutions that train the tourist guides.
