The main aim of the study was the description of the research on the presence of female directors on boards of the Polish listed companies and the relationship between gender diversity of their supervisory boards and management boards on financial performance. The outcomes of the research are: the negative influence of the company size on the number of women in supervisory boards, the positive influence of the management board members’ share in the ownership of the company on the number of women on supervisory boards, a negative influence of institutional investors’ share in the ownership of the company on the number of women on supervisory boards and the positive influence of the total number of boards members on the number of women both on supervisory and management boards. It was also confirmed that the number of women on both boards depends on the sector and there are more women on boards of banks. In addition, the other research allowed to confirm that gender diversity of the supervisory boards affects accounting measures of performance (ROA and ROE). But there was no relationship between gender diversity of the supervisory boards and the market measure of performance (TSR). Moreover, there was no relationship between gender diversity of the management boards and firm financial performance
