Introduction: The ever-expanding scope of psychological science and its influence on various social, economic, and industrial fields have transformed the structure of societies and people's relationships with each other. These issues are complex and cannot be easily resolved through logic. Therefore, over the last two decades, sports psychology research has honed in on understanding how psychological and personality factors impact athletes' performance. Researchers suggest that the intense and high-pressure environment of sports, particularly in championship competitions, results in athletes experiencing stress and psychological pressure. Therefore, the aim of this study was to explore the relationship between sports perfectionism and burnout among student-athletes.
Methodology: This research is practical and, based on the data collection method, falls under the categories of descriptive and correlational research. The statistical population consisted of student-athletes participating in futsal, basketball, and volleyball in Tehran province. The sample size for this study was 226 athletes. Data was collected using the Athlete Burnout Questionnaire (ABQ) and the Sport Multidimensional Perfectionism Scale-2 (Dunn et al., 2010).

Results: The Kolmogorov-Smirnov test indicated a normal distribution of the data. The Pearson correlation coefficient test revealed a significant negative relationship between overall scores and components of sports perfectionism (Personal Standards, Concern over Mistakes, Perceived Parental Pressure, Perceived Coach Pressure, Doubts about Actions, and Organization) with overall scores and components of burnout (physical-emotional exhaustion, reduced sense of accomplishment, and sport devaluation) (P<0.05).

Conclusion: The results suggest that an increase in perfectionism among athletes is associated with a decrease in burnout levels. Coaches and experts are encouraged to consider this psychological component to help reduce burnout among athletes.
