This study aims to analyze the problem-solving abilities of eighth-grade students at SMP Negeri 5 Loura after learning through the Contextual Teaching and Learning (CTL) model on relations and functions. This research used a descriptive qualitative approach involving 10 students as research subjects. Data were collected through tests, observations, interviews, and documentation, and analyzed based on four problem-solving indicators: identifying elements, modeling, applying strategies, and evaluating results. The results showed that most students were able to understand the concepts of relations and functions, determine domain and range, and represent relations using arrow diagrams and ordered pairs. However, some students still experienced difficulties in mathematical representation and explaining their solutions. The implementation of the CTL model contributed positively to students’ conceptual understanding and problem-solving abilities by connecting mathematical concepts with real-life contexts
