The ability to think mathematically critically is essential in learning as it helps students to think rationally in making decisions and formulating conclusions, as well as choosing the best option for themselves. In fact, PISA results in 2022 and TIMSS results in 2015 show that students' critical thinking skills are not optimum. Therefore, the role of educators is required in order to develop the critical thinking ability of students. Self-regulated learning can affect students' cognitive ability to think critically. The purpose of this research is to identify, study, and make overall related conclusions of research results related to the mathematical critical thinking ability reviewed from self-regulated learning. The method used in this study is the Systematic Literature Review (SLR). The data collection process involved merging similar research articles focused on topics of mathematical critical thinking and self-regulated learning published between 2019 and 2023. The article used in this study is 13 articles obtained from Publish or Perish. The findings results reveal a distinction in mathematical critical thinking proficiency based on students' level of self-regulated learning.
