This study evaluated the community relations and Corporate Social Responsibility (CSR) activities of oil marketers in Owerri Metropolis, examining their scope, effectiveness, and perceived impact. Guided by three research questions, the study adopted a survey research design. The population comprised approximately 1.07 million people, including residents of host communities and employees of selected oil marketing companies. Data were collected using a structured questionnaire and analysed through descriptive statistics. Findings revealed that oil marketers undertake CSR initiatives such as educational scholarships, health facility support, and minor infrastructural projects. However, these activities were found to be irregular, poorly sustained, and not consistently aligned with the actual needs of host communities. The study concludes that CSR in the oil marketing sector of Owerri Metropolis requires a more strategic, proactive, and participatory approach. Recommendations include conducting regular community needs assessments, establishing structured liaison mechanisms, and aligning CSR initiatives with broader sustainable development objectives.
