The rapid advancement of digital technology has encouraged the integration of various interactive learning media, one of which is YouTube. As a video-based platform, YouTube has the potential to enhance students' learning motivation by providing engaging, accessible, and flexible learning resources. However, empirical evidence regarding its influence on learning motivation in economics education at the senior high school level remains limited. This study aimed to examine the effect of YouTube use in economics learning on the learning motivation of tenth-grade students at SMA Negeri 4 Bone. A quantitative approach with an ex post facto research design was employed. The population consisted of 200 tenth-grade students, while a sample of 30 students was selected using the simple random sampling technique. Data were collected through questionnaires, observations, and documentation. The research instruments met the validity and reliability requirements and were analyzed using simple linear regression with IBM SPSS Statistics. The findings revealed that the use of YouTube in economics learning had a positive and significant effect on students' learning motivation. Furthermore, YouTube contributed to improving students' learning motivation, although other factors beyond the scope of this study also influenced students' motivation. These findings suggest that YouTube can serve as an effective learning medium to promote more engaging, interactive, and student-centered economics instruction. This study provides empirical evidence supporting the integration of digital learning media in economics education and offers practical insights for teachers in optimizing YouTube to enhance students' learning motivation.
