This study was embarked upon with a view to examining the need for peace in the management of tertiary institutions towards enhancing academic performance in south-south Nigeria. Three hypotheses and one research question guided the study. One thousand, two hundred and nineteen (1219) academic and non-academic staff were selected for the study. A 31 item researcher developed questionnaire was used to collect data from the sampled staff in their respective institutions. Population t-test and mean scores were used to analyze data collected. Findings show that peace was advocated but there were serious inadequacies in the implementation and enforcement process of peace. Proposed peace was scarcely enforced to the detriment of academic performance. The manner and approach to existing peace management does not actually address the issue of peace building. Based on the findings, recommendations were made which included among others, that conflict resolution and peace education courses should be introduced in the school curriculum.
