This study aimed to examine the effect of learning motivation and intelligence quotient (IQ) on students' learning outcomes, both partially and simultaneously. This research employed a quantitative approach with an ex post facto design. The data consisted of 30 students, including learning motivation scores, intelligence quotient (IQ) scores, and learning outcome scores. Learning motivation was treated as the first independent variable (X1), intelligence quotient (IQ) as the second independent variable (X2), and learning outcomes as the dependent variable (Y). Data were analyzed using descriptive statistics, Pearson correlation, multiple linear regression, t-test, F-test, and coefficient of determination. The results showed that the mean score of learning motivation was 75.43, the mean IQ score was 78.27, and the mean learning outcome score was 80.17. Multiple linear regression analysis produced the equation Y = -3.820 - 0.199X1 + 1.265X2, with a coefficient of determination (R²) of 0.963. The F-test indicated that learning motivation and IQ simultaneously had a significant effect on students' learning outcomes (F = 350.842; p < 0.001). Partially, IQ had a significant effect on learning outcomes (t = 10.204; p < 0.001), whereas learning motivation did not show a statistically significant partial effect at the 5% significance level (t = -1.819; p = 0.080).
