Corrections in Nigeria
A federal Nigerian Correctional Service — with one of the lower imprisonment rates on this site, but a system above its stated capacity.
Facts on this page were checked against their sources on .
Prisons in Nigeria are run federally by the Nigerian Correctional Service (renamed from the Nigerian Prisons Service by a 2019 Act, which added a non-custodial arm); "Prisons" is a matter on the Exclusive Legislative List, so there are no state prison services. Because the system is federal, a figure for the whole system describes the whole system.

- What is justice?
Justice is the principle that people should be treated according to rules that apply equally to everyone, decided by bodies that are authorised, constrained, and answerable. This guide explains what that means institutionally.
- Why do justice systems need oversight?
Justice institutions hold coercive powers, often operate out of public view, and make decisions that are hard to reverse. This guide explains the oversight mechanisms built to detect and correct errors, and their limits.

The World Prison Brief country page for Nigeria (compiled by ICPR from the national prison administration, the Nigerian Correctional Service), read directly and re-confirmed by hand. Supports: a total prison population of 81,902 including pre-trial detainees at 22 June 2026; a rate of 34 per 100,000 based on an estimated national population of 238.95 million at mid-2026 (UN figures); an official capacity of 65,035 dated 30 June 2025; and an occupancy level of 125.6% dated 30 June 2025. The population figure is dated June 2026 while the capacity and occupancy carry a June 2025 date, so the figures do not share a single reference date.
