This study aimed to describe the students’ problem-solving ability in solving Geometry problems. This research was a qualitative descriptive study with 6 students as research subjects at SMP Negeri 1 Piyungan Bantul. The data collection methods used in this research were tests and interviews. This research used the triangulation method to determine the validity of data which was obtained by the researcher. The results showed that the percentage score for the indicator of understanding the problem was 31.48%, planning strategies to solve problems was 57.41%, implementing strategies to solve problems was 55.56%, and concluding by 31.48%. At the level of problem-solving ability, there is one high category student, 3 medium category students, and 2 low category students. This is because students lack self-confidence, lack of understanding of problems, weakness in understanding concepts, principles, and mathematical formulas of geometric material, and lack of skills in calculations. Therefore, it is necessary to provide more and more complex questions so that students are familiar with various kinds of non-routine questions. Also, it is necessary to have an understanding of mathematical concepts, principles, and formulas so that they do not have a negative impact on students in solving advanced material geometry problems.
