This study examined the relationships between school climate, school belonging, and school burnout in secondary students. 667 middle school students from the Dörtyol district of Hatay, selected through a stratified sample, participated in the study. School Climate Scale, School Belonging Scale, and School Burnout Scale were used to collect data. Descriptive statistics, regression analysis, path analysis, and Sobel test were used to analyse the data. The study's findings show that secondary school students' perceptions of school climate and belonging are high, and their school burnout levels are medium. Additionally, the research findings show significant relationships between school climate, school belonging, and school burnout. School climate and school belonging are significant predictors of school burnout. School belonging has a mediating effect on the relationship between school climate and school burnout. School climate, which has a significant impact on the school burnout of secondary school students, has this effect directly and indirectly through school belonging.
