The study aimed to explore the relationship between corporate governance (i.e., tasks and responsibilities of the Board of Directors, disclosure and transparency, shareholders’ rights and fair treatment of shareholders, and audit and internal control) and bank performance. Data were collected using a questionnaire distributed to a sample consisting of managers of commercial banks in the northern region in Jordan. The study found a significant and positive relationship between corporate governance and bank performance. Particularly, the study pointed out two principles (i.e., tasks and responsibilities of the Board of Directors, and audit and internal control) were positively related to bank performance, while there were no significant relationships between the other two principles (i.e., disclosure and transparency as well as shareholders’ rights and fair treatment of shareholders). It was concluded that corporate governance is very critical for enhancing bank performance. Additionally, commercial banks should pay more attention to all principles of corporate governance.
