The purpose of this study is to examine the relationship between green entrepreneurial orientation and sustainable firm performance. In order to examine this relationship, meta-analysis method was used and analyses were carried out with Comprehensive Meta-Analysis Software (CMA) v4 package programme. In the study, a sample of 23 articles, 42 effect sizes and 6666 enterprises was reached through a systematic literature review. The studies included in the research were accessed by searching the keywords "green entrepreneurial orientation" and "sustainable firm performance" from Web of Science, EBSCO Host, Scopus and Google Scholar databases and only articles were included without any year limit. Throughout the study, statistical analyses were performed on Fisher z values and conducted under the random effects model. The effect size, heterogeneity and publication bias analyses of green entrepreneurial orientation and sustainable firm performance and its sub-dimensions were tested separately, and the findings were interpreted by converting them into correlation coefficients. As a result of the analyses, it was found that the relationship between green entrepreneurial orientation and sustainable firm performance is positive and highly significant. In addition, the relationship between financial, environmental, social, sustainable and entrepreneurial performance, which are the sub-dimensions of sustainable firm performance, and green entrepreneurial orientation was found to be high and significant. However, it was concluded that there is no significant relationship between green innovation performance, which is another dimension of sustainable firm performance, and green entrepreneurial orientation.
