This study examined poverty-insecurity nexus as an impediment to peace and development in Borno State with a focus on Boko-Haram. Violent attacks by Boko Haram has plunged the state into a chronic state of insecurity. This study adopted a descriptive research design. Data were collected from secondary sources such as journal articles, books and documented cases related to poverty and insecurity. Findings of the study revealed that in Borno State insecurity has claimed a lot of lives and property; compounded the food and nutrition insecurity, denied millions of children and youths access to education; increased the number of internally displaced persons and caused people to live in constant fear and anxiety. Based on the findings the study recommended that, there should be reduction in poverty and inequality through the provision of employment opportunities and the provision of basic infrastructure and services that are efficient. There should also be inclusive economic growth policies focusing on job creation, particularly in agriculture, manufacturing, and the informal sector, to address unemployment and income inequality.
