This study contributes to our understanding of employee behavior in governmental organizations. This paper aims to demonstrate the effects of organizational culture, transformational leadership, and work motivation on organizational citizenship behavior (OCB). This paper also aims to conduct a literature evaluation on the OCB of the public sector, using VOSviewer to acquire a visual representation of the research's progress. The VOSviewer for visualizing research progress adds value by providing a clear and intuitive representation of the scholarly landscape. Visualizing connections and clusters among documents can facilitate the identification of key themes and research directions. The study searched the Scopus database using the keywords "organizational citizenship behavior public sector," resulting in the discovery of 85 relevant documents. The study analyzed documents published between 2019 and 2023. Afterward, the study selected 25 documents with the highest rankings as references using Publish or Perish. Supplementary documents were discovered through Google Scholar and Proquest. In comparison to other studies, this research is more diverse in the variables, providing integrated information in the public sector. Consequently, this research remains pertinent. Nevertheless, the amount of study conducted on OCB in the public sector has been limited. Therefore, there is a potential for further investigation in this field. The main findings of the study demonstrate that (i) underscore the relevance of promoting a positive organizational culture, fostering transformational leadership, and enhancing work motivation to encourage OCB among public sector employees and finally (ii) the results of this study indicate that influential factors have a positive impact significantly on the OCB in the public sector.
