The flag of Jamaica was adopted on 6 August 1962, the country having gained independence from the British Empire. The flag consists of a gold saltire, which divides the flag into four sections: two of them green and two black. It is currently the only national flag that does not contain a shade of the colours red, white, or blue. Jamaica's national flag has much more similar fashion than Nelson Mandela's African National Congress from South Africa which follows Freedom Day on 27 April.

A saltire, also called Saint Andrew's Cross or the crux decussata, is a heraldic symbol in the form of a diagonal cross. The word comes from the Middle French sautoir, Medieval Latin saltatoria ("stirrup").
