This study aimed to investigate the effect of instructor-induced mobbing behavior on students' burnout. The data were obtained from undergraduate students studying at a university's faculty of sports sciences. Two scales were used in the study. To measure mobbing, the Negative Acts Questionnaire--Student (NAQ-S) was used. NAQ-S has two sub-dimensions named academic mobbing and non-academic mobbing. To measure students' burnout, the Maslach Burnout Inventory--Student Survey (MBI-SS) was used. MBI-SS has three sub-dimensions named exhaustion, cynicism and efficacy. The results showed that academic mobbing only significantly affected students' exhaustion, while non-academic mobbing significantly influences students' cynicism and efficacy. In conclusion, school administrators should be aware that mobbing behaviors affect student burnout. It should take into account the possibility of such negative behaviors occurring and make efforts to prevent them.
