This research aimed to analyze students’ creative thinking skills in solving mathematical logic problems. The approach used in this research is the open-ended approach. This research is a qualitative descriptive study. The subjects in this research were students at Mathematics Educations study program in Faculty Education and Teacher Training at State Islamic Institute of Jember. Data collected in this research are test results with open-ended question types, interview results, observation results, and documentation during the research activities. The data analysis technique used in this research is the Miles and Huberman analysis model.
