The methodology of this study is a quantitative and ex-post and the sample of this research is related to 153 companies on the TSE. The results of research regression analysis showed that there is a negative and significant relationship between firms’ board gender diversity and their financial statements fraud. The results also showed that in the group of non-state firms, there is a negative and significant relationship between firms’ board gender diversity and their financial statements fraud, but this relationship is not significant in the group of state-owned firms.
