This research explores the role of Organizational Citizenship Behavior (OCB) in enhancing employee performance at the Commercial Bank of Ethiopia, Woldia District. Despite prior studies on OCB, there is limited evidence on how its various dimensions influence performance in the Ethiopian banking sector. To address this, a quantitative, descriptive-causal research design was employed, collecting data from 228 employees. Participants were selected using stratified sampling to group employees by job roles, followed by simple random sampling. Data analysis was conducted using correlation and multiple linear regression methods. The results show that OCB dimensions—helping behavior, sportsmanship, civic virtue, organizational loyalty, and individual initiative—positively and significantly impact employee performance. The study highlights the importance of fostering a collaborative culture, promoting individual initiative, and acknowledging exemplary citizenship behaviors to improve workplace effectiveness. The findings provide both theoretical contributions, by extending understanding of OCB in banking contexts, and practical guidance for enhancing employee performance and organizational outcomes.
