This study aims to determine the effect of using scientific e-comic learning media on students' critical thinking skills in Earth and Solar System subjects. The type of research used is a pre-experiment with a One Group Pretest-Posttest design. The research subjects were 29 students in class VII-B of SMP Negeri 2 Berbek, selected through purposive sampling. Data were collected through critical thinking ability tests, student response questionnaires, and documentation, and then analyzed using a quantitative approach with inferential statistical tests. The results of the study showed an increase in the average score from 65.5 on the pretest to 79.3 on the posttest. Students' responses to learning using scientific e-comics were in the very good category with an average score of 4.2 (84%). The significance test showed a significant effect of the use of this media on the improvement of critical thinking skills. This study confirms that scientific e-comics can be an alternative learning medium that is interesting, interactive, and effective in supporting the development of students' critical thinking skills.
