This paper interrogates the challenges of national integration in Nigeria. Several policies and programmes of government like harmonized state structure, establishment of National Youths Service Corps Scheme, Federal Character Commission have not been able to achieve the goal of unifying the peoples of Nigeria. The question is, what are the factors responsible for lack of unity, tribalism, nepotism, electoral malpractices, anarchy and social disorganisation, which are the bane of the Nigerian soda-political structure today? This paper provides answers to this question. It exposes the intricacies of national integration and seeks to x-ray the factors which hinder the realization of the dream of national integration and their possible alternatives. The identified alternatives deal with how to achieve the objective of national integration in Nigeria.
