:This study aims to analyze the role of good corporate governance in the relationship between family ownership and institutional ownership with related party transactions. The research population uses mining companies that issue their shares on the Indonesia Stock Exchange in the 2017-2021 period with purposive sampling. Based on data from 155 companies' annual financial reports using multiple regression analysis, it was found that family ownership, good corporate governance, and the interaction between family ownership and good corporate governance have an effect on related party transactions. Meanwhile, institutional ownership and the interaction between institutional ownership and good corporate governance have no effect on related party transactions. These results indicate that institutional ownership of companies in Indonesia has not been able to carry out the monitoring process effectively and tends to follow the wishes of the company's management
