Abstract: This study aims to study the relationship between motivating employees of commercial banks and customers satisfaction in Libyan commercial banks. It adopts a quantitative approach, using questionnaires to collect the required data from two groups: Bank Employees and Customers. The findings of this study provide that there is a positive direct relationship between the component of motivation service providers in the Libyan commercial banks as one of the most important internal marketing component (the independent variable) and customer satisfaction in those banks. The study has shown that Libyan banks do not give much attention to motivation programs for banking service providers that are appropriate with work requirements and skills acquisition.
