The aim of this study is to determine the correlation between moral disengagement level of team athletes and unethical behaviors they perceived from their coaches by examining moral disengagement level of team athletes depending on unethical behaviors they perceived from their coaches. The target population of the study consists of 305 team athletes whose age average is 20.45 [plus or minus] 4.68 and who are training with the same trainer for average of 2.01 [plus or minus] 1.69 years and from basketball, football and volleyball branches. In this study, "Moral Disengagement in Sport" and "Athlete's Perception about Coaches' Unethical Behaviors" scales have been used as data collection tools. Descriptive statistics, t test, ANOVA and Pearson Correlation analysis were used for the analysis of data. According to the findings of the study, it was observed that there was a positive low level of correlation between moral disengagement and athlete's perception about unethical behaviors of the coach. Younger athletes have a higher perception about unethical behavior they perceived from coaches. Moral disengagement scores of male athletes, athletes who did not take part in national team and athletes who were punished were significantly higher. Significant difference was observed in moral disengagement and in the sub-dimensions of the athletes' perception about their coaches' unethical behavior scales by branch. When the meeting level of athletes with their coaches in the social environment examined, it was seen that there was a significant difference in all sub-dimensions of the athlete's perception regarding the coach's unethical behaviors scale. When athlete's level of communication with their coaches was examined, there was a significant difference in all sub-dimensions of the athlete's perception regarding the coach's unethical behaviors scale. As a result, as the level of unethical behavior that athletes perceived from their coaches increases, the level of moral disengagement also increases.
