Conflicts and insurgencies constitute some of the greatest challenge to societal peace and development. While daily effort are made by government and humanitarian organisations to address the problem of conflicts and insurgency, the absence of quality health service for those affected by conflicts have further amplified the potential for conflicts and human insecurity. The paper examines conflict and insurgency as barrier to quality health service for internally displaced persons in the North Eastern part of Nigeria. It argues on the failure and inability of the Nigerian government to respond to the exigency of conflicts and insurgency, tugging on instability which affects quality health services. Access to global quality health services has become unattainable and inaccessible and the implication for the worsening health conditions of internally displaced persons in Nigeria. As the outcome of a qualitative research carried out to interrogate the impact of conflict and insurgency on global quality health services on internal displacement persons, its methodology relies heavily on in-depth and key informant interviews. The paper concludes that unless concerted effort through legal and political will are put in place to address the problem of conflict and insurgency in the northern part of the country, especially with the growing activities of Boko Haram and farmer-herders conflicts, quality health service will become unattainable, especially for internally displaced person who are not only victims of insurgency, but also vulnerable to poor quality service in the process of their integration and durable solution.
