This study investigates the relationship between academic self-efficacy and mathematics anxiety in upper grade students of elementary schools in Sidoarjo. A total of 185 students from two schools participated in this study. The academic self-efficacy and mathematics anxiety scales were employed for data collection. Using saturated sampling analysis, a significant negative correlation coefficient of -0.248 (p < 0.001) was found, indicating a negative association between academic self-efficacy and mathematics learning outcomes. The students exhibited a moderate level of academic self-efficacy (43%) and mathematics anxiety (39%). The implications of these findings contribute to our understanding of the interplay between academic self-efficacy and mathematics anxiety among upper grade students, thereby offering valuable insights for educators, policymakers, and researchers to enhance mathematics education strategies and support mechanisms.
