This study aims to analyze the profile of elementary school students' critical thinking ability in mathematics learning and identify differences based on gender. The research was conducted at SDN Pucungkidul 1 Tulungagung, involving 30 fourth- and fifth-grade students selected through purposive random sampling. Data collection was carried out using a critical thinking ability test, which consisted of five indicators: problem interpretation, conceptual analysis, argument evaluation, logical inference, and metacognitive reflection. The data were analyzed quantitatively using descriptive statistics to observe the students' average score trends, and a comparative test was conducted to identify differences based on gender. The findings indicate that the conceptual analysis indicator had the highest score, while metacognitive reflection had the lowest score, suggesting that students still struggle to evaluate their own thinking processes. Additionally, there was a tendency for differences in critical thinking abilities between male and female students, although statistical tests showed varying levels of significance. These findings imply the need for more adaptive and reflective learning strategies to enhance students' critical thinking awareness in mathematics learning.
