The study aims to demonstrate the impact of adopting professional information ethics on business performance in Jordanian banks. The researcher developed a questionnaire from previous studies; it included (45) items to collect data from the study sample. A regular stratified sample of employees in Jordanian banks was chosen with (350) employees distributed among managers, heads of departments and employees. The results indicated that there is a statistically significant impact of adopting professional information ethics on business performance in general and achieving profits and developing services, which in turn has a positive impact on preserving information as a resource, goal and product for Jordanian banks. The study recommended increased attention to information ethics and the training and development of employees on its importance and application in the performance of their daily work. As far as the researcher knows, this is the first study that indicates the extent of the commitment of employees in Jordanian banks to the ethics of information and the extent of its positive reflection on business performance, since other studies discussed the ethics of electronic business and its impact on the performance of money in banks.
