The purpose of this study was to determine the effect of implementing good corporate governance on financial performance in banking companies. Proxies for good corporate governance are the board of directors, the independent board of commissioners, the audit committee, external audit quality, and institutional ownership. Measurement of banking financial performance uses Return on Assets (ROA). The sample used is 26 samples of banking sector companies listed on the IDX during 2014-2018. The analysis technique uses multiple regression analysis. The results showed that the board of directors and institutional ownership have an influence on financial performance, while the independent board of commissioners, audit committee, and external audit quality have no influence on financial performance.
