This study examines the impact of traditional rulers on public security enhancement in the Northern Senatorial District of Adamawa State, Nigeria, stressing their crucial role in the enhancement of public security and the maintenance of peace amidst growing security challenges in the zone, such as insurgency, banditry, and ethnic conflicts. The research adopted a survey research design. The study population comprises all the inhabitants of five local government areas that make up the northern senatorial district of Adamawa State, namely Mubi North, Mubi South, Maiha, Madagali, and Michika. 384 questionnaires were distributed to the respondents, of which only 362 were completed and retrieved successfully. The data collected were presented and analyzed in tabular form, and hypotheses were tested using regression analyses with the help of the Statistical Package for Social Sciences (SPSS ver. 23.0). The regression coefficients offer valuable insights into the impact of various factors on the enhancement of public security in the Northern Senatorial District of Adamawa State. The role of Traditional Rulers (TR) shows a coefficient of 0.528 (p < 0.000), indicating a strong and significant positive contribution to public security. However, the study recommends that there is a need to encourage capacity building and training in terms of incessant training programs for traditional rulers to update their skills and knowledge in modern public security management, grant legitimate powers to traditional rulers on public security matters, conflict resolutions, and community policing for arrests and prosecutions where necessary to make them well[1]equipped to manage security issues for an effective enhancement of public security in their domains.
