Africa Environment Day, celebrated annually on 3 March, was established by the Organization of African Unity in 2002 as a way of raising awareness of the pressing environmental challenges facing the continent.

Since 2012, the Africa Environment Day has been celebrated in conjunction with Wangari Maathai Day, as a tribute to the late Nobel Laureate's green legacy.
