This research work with the title, “Leadership in the Health Sector: A Discourse of the Leadership Model of Utilitarianism,” is concerned with examining the appropriateness of Utilitarianism as a leadership model that may be employed and utilized by leaders in the public health industry. The research is predicated on the proposition that leadership is as much a problem in the health industry as it is for all humanity. Most leaderships fail due to the employment of inappropriate leadership theories. The appropriateness of any leadership model can only be determined after the model has been subjected to adequate critical analysis. Hence this research adopts the philosophical methods of exposition and criticism in unravelling its subject matter. This research is significant in exposing a leadership model with an underlying ethical content which can serve as a paradigm for leadership and decision making in the health industry. The paper identifies the control and management of HIV/AIDS as well as the enhancement of National Health Insurance Scheme (NHIS) coverage in third world countries as critical health issues that can be strengthened through the adoption of the leadership paradigm of utilitarianism. The paper concludes that the utilitarian normative axiom of the greatest happiness for the greatest number will ultimately lead to the engendering of democratic culture in the policy and decision making processes bordering on health issues. However, the work cautions that the majority principle enshrined in axiom of utilitarianism is all too vulnerable to abuse by any leader with a totalitarian bent. Hence a leader who adopts utilitarianism as a normative principle is advised against allowing the good of the majority to always supersede and dominate that of the minority.
