<![CDATA[Teacher performance is one of the most important indicators in determining educational quality. Various studies have shown that principal leadership significantly influences teacher performance. However, this influence does not always occur directly but may operate through psychological factors, one of which is work engagement. This study aims to analyze the role of work engagement in mediating the influence of principal leadership on teacher performance through a literature review approach. The method used was a literature review by examining 10 scientific articles from SINTA-indexed national journals and reputable international journals published between 2021 and 2026. Data were collected through Google Scholar and Scopus databases using keywords relevant to the research variables. Data analysis employed content analysis by identifying, classifying, comparing, and synthesizing findings from the selected studies. The results indicate that principal leadership has a positive effect on teacher performance through increased work motivation, commitment, quality of the work environment, and learning effectiveness. Furthermore, work engagement was found to play a significant mediating role in strengthening the relationship between principal leadership and teacher performance. Teachers with high levels of work engagement tend to demonstrate greater dedication, enthusiasm, and involvement in carrying out their professional responsibilities, leading to improved performance. Therefore, strengthening work engagement should become a strategic priority for school principals in enhancing teacher performance and improving educational quality sustainably]]>
