Abstract: This study aimed to analyze the influence of learning motivation, peer environment, and learning facilities on the economics learning outcomes of tenth-grade students at SMA Negeri 1 Kualuh Hulu. The study employed an ex post facto method with a sample of 188 students selected using the Slovin formula. Data analysis techniques included multiple linear regression, t-test, F-test, and coefficient of determination (R²). The results showed that learning motivation, peer environment, and learning facilities partially and simultaneously had a positive and significant effect on students’ economics learning outcomes. Learning facilities were found to have the most dominant influence compared to the other variables. The coefficient of determination value of 86.7% indicated that students’ economics learning outcomes were influenced by learning motivation, peer environment, and learning facilities, while the remaining 13.3% was influenced by other factors not examined in this study.
