The aim of this study was to conduct a systematic review research concentrating on studies regarding "Mathematics anxiety." 59 papers were reanalyzed in order to answer the questions derived from the main aim in terms of the rules of systematic review method. These studies were reviewed and analyzed by taking account of their aims, designs, sampling and results. While doing this, the similarities and differences of the reviewed studies were also found. It was seen that most of these studies conducted with middle school students. It was also found that the majority of reviewed studies were designed according to quantitative approaches. The review shows that mathematics anxiety is resulted from students' achievement, self-efficacy and fear along with parents' and teachers' lack of supports in mathematics. The results gathered from reviewed studies suggest that studies designed with approaches like qualitative and mixed-method and studies focused on various topics related with "Mathematics anxiety" with different sampling are needed. In conclusion, this systematic review study provides some fruitful information for the area and so for the further studies.
