This paper examined the link between bad governance and perpetuation of insecurity in Nigeria. Using theoretical arguments, the paper holds that, the current security challenges that bedeviled Nigeria are attributable to injustice, corruption and selfish governance by the leadership class. Since Nigeria's return to democracy in 1999, after a lengthy military rule that lasted for almost three decades, incidences of ethnic, communal, religious and resource conflicts continue to persist across most part of the This is aggravated by the apparent failure of the leadership to address key issues affecting the country such as poverty alleviation, employment generation, resource allocation, infrastructural development etc. Thus, the paper concludes that tackling insecurity in Nigeria is an enormous task, but one which is not impossible. Therefore, Nigerians must unite and the governing class must develop a strong political will and total commitment to fighting insecurity.
