The Middle Belt or Central Nigeria is a term used in human geography to designate a belt region stretching across central Nigeria longitudinally and forming a transition zone between Northern and Southern Nigeria. It is composed of the southern half of the defunct Northern Region of Nigeria, now comprising mostly the North Central and parts of the North East and North West geopolitical zones, and is characterised by its lack of a clear majority ethnic group. It is also the location of Nigeria's Federal Capital Territory.
