The purpose of this study were (1) to describe the mathematical resilience of MTs Ats- Tsabat Makassar students.  (2)  to find out the factors that influence the mathematical resilience of MTs Ats-Tsabat Makassar students. This research is a type of mixed method research, namely research that uses two methods, quantitative and qualitative methods. The research design used was a sequential explanatory design, namely the collection and analysis of quantitative data in the first stage, followed by the collection and analysis of qualitative data in the second stage, which was built based on the initial quantitative results. The sample used in this study were 44 students at MTs Ats-Tsabat Makassar for quantitative data, and 6 research subjects were selected based on quantitative analysis to serve as a source of qualitative data. The instruments used were a mathematical resilience questionnaire for quantitative data and an interview guide as a tool for collecting qualitative data. The questionnaire used has undergone validation tests from experts and instrument trials, including validity and reliability tests. The study results show that: 1) The description of the mathematical resilience of MTs Ats-Tsabat Makassar students is that the average is in the medium category with a percentage of 50%. 2) The factors that influence the mathematical resilience of students at MTs Ats Tsabat based on the source of resilience I Have which means external support, it is found that family support factors and peer assistance factors determine the increase in students' mathematical resilience. Then from the second source of resilience I Am in the form of internal support are the interest factor, the independence factor, and the religiosity factor. Then from the I Can source that comes from social and intrapersonal interactions, it is found that communication skills and emotional management factors can affect mathematical resilience.
