The flag of Nigeria was designed by Michael Taiwo Akinkunmi and was officially adopted to represent the nation of Nigeria at midnight on 1 October 1960, the day the country gained independence. The flag was chosen as part of a nationwide open contest held by the government, with Akinkunmi's design being selected as the winner of a field of over three thousand entries. The flag is a vertical bicolour green-white-green design, with the green to represent agriculture and white to represent peace and unity.

The flag was raised for the first time in a ceremony by Lieutenant David Ejoor of the Army Guard.
