This research aims to analyze the effect of CEO power and board gender diversity on modern slavery disclosure (MSD) among Indonesia’s top 50 publicly listed companies by market capitalization. The research uses a quantitative approach with secondary data collected from annual and sustainability reports during the 2022–2024 period. The results show that CEO power has a negative and significant effect on MSD, indicating that stronger CEO power will reduce disclosure transparency. Furthermore, gender diversity on the board of commissioners also shows a negative and significant relationship with MSD, indicating that female representation in supervisory roles has not yet contributed into greater social accountability within Indonesian firms. Meanwhile, gender diversity on the board of directors shows no significant effect. These results suggest that internal governance factors such as CEO power and limited female influence in top positions still hinder companies from being transparent about social and ethical issues. In conclusion, stronger regulations and independent oversight are needed to improve companies’ transparency regarding modern slavery practices.
