This position paper looked at refocusing public universities for peace and national security. It will amount to great insensitivity to ignore current social, political and economic maladies that constitute huge threats to peace and national security in Nigeria as of today. Prevalence of peace and security are imperative for peaceful coexistence and sustainable development of a pluralistic society like Nigeria. Challenges whether natural or man-made, exist in every organised human society. Refocusing public universities is pivotal in addressing some contemporary issues threatening the coexistence of all the major and minor tribes constituting Nigeria. The concepts of Peace and Peaceful Society, Security; Civic Education; Entrepreneurial Education were highlighted. This article also discussed Factors that Threaten Peace and National Security; Absence of Peace and National Security Implications; Resources required to enable Public Universities Promote Peace; Justification of University Education for Peace and National Security. This write-up also concluded that since it is incumbent on any legitimate government to provide basic infrastructures, security of lives and property for peaceful co-existence among others through her established agencies, bodies, organs and institutions, she should in similar vein use any one of these establishments to analyse any identified challenging issue begging for solutions. The position of this paper is that public university institutions in Nigeria should be saddled with the responsibility of proffering solutions to the threats of peace and national security. This paper therefore recommends that these universities should make Entrepreneurship Education for skills acquisition and Civic Education for value orientation compulsory, for all undergraduate students enrolled and all profiled restive youths in our communities that will benefit from this proposed project through university community service mounted programmes.
