Some students consider mathematics as a subject that is very difficult and frightening, so it results in the success of learning mathematics. There are two factors that cause students' success in learning mathematics, namely internal and external factors. Students' attitudes is one of the internal factors that determine the success of learning mathematics. This study aims to prove the effect of student attitude on mathematics learning success. This type of research is quantitative meta-analysis. The variables of this study are students' attitudes as independent variables and students' mathematics learning success as dependent variables. Sources of data obtained from various research results in Indonesia since 2010-2019. Twenty-two samples of research publications were taken from online databases (google scholar, national & international journal) according to specified eligibility criteria. Data analysis using a meta-analysis approach. The results showed that there was a positive and significant influence on students' attitudes towards mathematics learning success, with the weight value of the effect size being within the specified confidence interval. The small amount of sampling error causes the effect size weight to be in the moderate category. These results have of course proven consistency and strengthened the theories or findings of previous researchers.
