The study investigated the relationship between media resources utilization and post-graduate students' research outputs in Nigerian federal university librarues. A sample of 2,016 postgraduate students was selected from a population of 40,328 from six universities. Data was collected using observation checklists and structured questionnaire, with a response rate of 77.5%. The results showed a low relationship between media resource utilization and postgraduate research outputs. Availability of hard disk drives, computers, and Internet was found to be 9.7%, but the utilization level fell below the benchmark of 2.5. The challenges include irregular electricity supply and poor Internet connectivity. The null hypotheses of no significant relationship were rejected. The study concludes that university libraries, particularly in developing countries, are crucial for impactful scientific research globally, with ICT playing a key role in building knowledge, facilitating learning, and increasing collaboration. The National Universities Commission should ensure allocation of adequate funds for the provision of media resources in the library for quality research output by postgraduate students
