This study aimed to analyze the effect of employee satisfaction on employee performance, and the moderating role of organizational commitment in Jordanian Islamic banks. This study was conducted using a self-administered questionnaire distributed among employees from four different Islamic banks in Jordan. A total of 303 responses were collected and analyzed using SPSS and partial least square. A significant relationship was found between employee satisfaction and employee performance. There was also a significant effect of the moderating role of organizational commitment on the relationship between employee satisfaction and employee performance. One potential reason to support this relationship is that individuals who are satisfied with their performance tend to be happier and need a commitment from the organization to improve their work performance. The finding from correlation analysis shows that implementing the idea of organizational commitment illustrates the role that it plays in achieving employee satisfaction while doing their desired work. On the other hand, this suggests that increased organizational commitment in Jordanian Islamic banks increases employee performance significantly, which can enable each bank's management to achieve its targets, missions, and visions. The study is useful for the banking sector, financial institutions and other organizations in any country that seek improvements in employee performance.
