The defence force is important to the well-being, safety, and security of a nation. The availability of competent military personnel maintains national security and enables the country to withstand external threats to safety and security. The purpose of this study was to investigate the influence of organizational justice and psychological ownership on the turnover intention of the Namibian Defence Force (NDF) personnel in Namibia. Understanding turnover intention assists organizations to reduce the influence of turnover, reduce additional expenses related to recruitment, training, and development, and enhance the overall performance of the organization. A quantitative research design (survey) was used to collect data on Namibian Defence Force personnel (n=325). The study found a negative relationship between organizational justice and turnover intention as well as between psychological ownership and turnover intention. A positive correlation was found between organizational justice and psychological ownership (excluding accountability). This study recommends that the organizational culture and working environment be improved to foster inclusivity, collaboration, mutual respect, and improved communication. With enhanced environment and working relationships, employees are likely to experience higher levels of organizational justice, psychological ownership, and reduced levels of turnover intention. This study adds to the limited literature on these variables and on the NDF in Namibia. Keywords: organizational justice, psychological ownership, turnover intention, Namibian Defence Force.
