This study aims to investigate the impact of Good Corporate Governance (GCG) on the financial performance of sharia banking. GCG is measured by the Board of Commissioners Performance, the Board of Commissioners Composition, the Number of Audit Committees, the Board of Directors, and the Sharia Supervisory Board Performance, whereas financial performance is proxied by Return on Assets, financing risk (Non-Performing Financing), and capital (Capital Adequacy Ratio). Sharia commercial banks registered by Bank Indonesia made the sample of this study. Annual reports and GCG reports of sharia commercial banks from 2014 to 2017 are used as a data source. The study uses a panel data regression approach to analyze the data; some interesting results have been obtained. The Sharia board positively affected financial performance of Islamic banks in terms of return on assets and capital adequacy ratio, and negatively as to non-performing financing. Similarly, the board of directors had a significant impact on the financial performance of Islamic banks in the same direction as the sharia supervisory board in terms of the three components. Meanwhile, the board of commissioners had a significant and positive impact only on the return on assets of Islamic banks in Indonesia.
