This study is aimed at investigating the mediating effect of organizational commitment on the relationship between organizational citizenship behavior and organizational culture with good governance among civil servants in Malaysia. This cross-sectional study involved 207 departmental records officers from 27 ministries in Malaysia selected through stratified random sampling. Data were collected from self-administered questionnaires. The results of the study indicated that there was a significant relationship between organizational citizenship behavior and organizational culture with good governance. Organizational commitment mediated both relationships. The findings of the study could provide useful recommendations for ministries/departments to ensure that aspects of organizational citizenship behavior and organizational culture are integrated with planning and implementing best practices in records management in the Malaysian public sector.
