Corporate governance is how companies are run and who keeps an eye on them. It talks about a wide range of things, such as directors' duties and how investors, directors, and auditors work together. This study aims to figure out if different types of governance positively affect the performance of Palestinian banks from 2015 to 2019. Ideally, this would lead to empirically-based policy suggestions. This study uses descriptive analysis methods to look at the essential parts of the relationship between corporate governance and the performance of selected banks with financial metrics. According to this study, the size of the board of directors significantly affects the return on equity in Palestinian banks. which means that when the board of directors has more members, they have more say over who owns the bank. This is shown by the return on equity, which shows how little power the board of directors has.
