Abstarct: The aim of this study was to examine the impact of team identity on athlete burnout with the mediating role of social support. The research method was descxriptive-correlational and cross-sectional in nature. The statistical population of the study included all football plaxyers from Baghdad province, with a sample of 231 plaxyers selected through convenience sampling. The research utilized three standardized questionnaires: Team Identity (Bourner & Benson, 2018), Burnout (Raedeke & Smith, 2001), and Social Support (Kafi et al., 2016). To assess the validity of the research instruments, the opinions of ten experts and professors in sports management were consulted, and the reliability of the instruments was confirmed using Cronbach's alpha coefficient. Structural equation modeling with a variance-baxsed approach was used to test the hypotheses. Data analysis was performed using SPSS23 and Smart-PLS 4 software. The results indicated that both team identity and social support have a significant negative impact on athlete burnout. Additionally, social support was found to have a mediating role in the relationship between team identity and burnout. The findings highlight the importance of team identity and social support as key factors in reducing athlete burnout. Specifically, the results showed that fostering a strong team identity within sports teams can help reduce burnout levels, with this effect being strengthened through social support among athletes. baxsed on these results, it appears that strengthening social relationships and mutual support within the team, especially in professional and youth sports teams, can improve the psychological and physical well-being of athletes. In this regard, coaches and team managers can focus on creating a positive team identity and providing a supportive environment for athletes to prevent burnout and enhance team performance.
