The Nigerian National Sports Festival is a biennial multi-sport event organized by the Federal Government of Nigeria through the National Sports Commission for athletes from the 36 States of Nigeria.
Started and stagged in 1973 at the National Stadium, Surulere in Lagos, the game was originally conceived as a "unifying tool" with the main purpose of promoting peace and cross-cultural affiliation in Nigeria after the Nigerian Civil War in 1970. The game also serves as a development and training event to aid athletes prepare for continental and international meets.
