This study aims to test the impact of strategic planning on enhancing the strategic performance of Bahraini banks. The study has two variables. The strategic planning as an independent variable includes a group of four perspectives, namely environmental scanning, strategy formulation, strategy implementation, and strategy evaluation. The strategic performance as a dependent variable also includes a group of four perspectives: financial, customer, internal business process, and learning and growth. The sample of the study consists of the employees of 10 of all the 12 commercial banks in Bahrain. A questionnaire was developed to gather the data. Five questionnaires were distributed to each bank totaling 50 questionnaires. The results showed that the strategic planning has a good statistically significant impact on financial, customer, and learning and growth. The results also showed a medium statistically significant impact of strategic planning on internal business process. The research recommended focusing on all aspects of the strategic performance in the banks under study, specifically the internal business process perspective.
