This research was conducted to examine the relationship between the trait anxiety levels of national sailing athletes and their mental toughness levels and to investigate the effects of some variables on the athletes' trait anxiety and mental toughness levels. The research universe consists of national athletes competing in different disciplines affiliated with the sailing federation. The sample comprises 32 national athletes (Kitesurfing, windsurfing, and centerboard classes) who voluntarily participated in the research. In addition to the Demographic Information Form, the "Sports Mental Toughness Inventory" and "State-Trait Anxiety Inventory" were used in the research. As a result of the analysis of the data, it was seen that the confidence level of the male athletes was higher than the female athletes, the control levels of the female athletes were higher than the male athletes, and the confidence levels of the kitesurfing athletes were higher than centerboard and windsurfing athletes. In addition, there was a positive and moderate relationship between the age of the athletes and the duration of doing sports and competition. At the same time, there was a negative and moderate relationship between age and the control sub-dimension and between confidence and the control sub-dimension.
