This study aimed to analyze the students’ mathematical critical thinking skill on the two-variable linear equations system. This research is a descriptive study with a qualitative approach. The subject of this study was 32 students of grade 8 in Junior High School Satu Atap 3, Jati Agung, Lampung. The data collection techniques used Critical Thinking Instrument with two problem descriptions. Furthermore, the data collected was analyzed based on indicators of critical thinking skill set by the researchers which included interpretation, analysis, evaluation, and inference. Based on the data analysis, the average of critical thinking skill of students is 52.15%, in the low category. The percentage of interpretation aspects is 53.13%, in the low category, the analysis aspect is 52.73% in the low category, the evaluation aspect is 54.30%, in the low category, and the inference aspect is 48.44%, in the low category. The results of this study indicated that the students’ critical thinking skills are still low so it is expected that by knowing these conditions the teachers and researchers are able to choose, design, and develop the learning that facilitates the students to practice critical thinking.
