Super Falcons of Nigeria beat Cameroon 2-0 to win the African Women’s Championship in Windhoek, Namibia, on Saturday.
Desire Oparanozie scored the first goal for Nigeria after 12 minutes with a superb free kick.
Asisat Oshoala sealed the victory by scoring Nigeria’s second goal two minutes from the end of an enthralling first half.
Only twice since the inaugural African Women’s Championship in 1991 have the Nigerians failed to win the trophy.
Equatorial Guinea are the only other winners – in 2008 and 2012 – but failed to qualify for this year’s tournament.
Cameroon coach Enoh Ngatchu said reaching the World Cup for the first time in a decade can help transform the game in his country.
Ngatchu told BBC Sport: “We have more girls playing soccer, we are better organised – with this qualification, many things will change.”
Nigeria and Cameroon had already qualified for next year’s World Cup in Canada by reaching the final.
They will be joined there by Ivory Coast who beat South Africa 1-0 in the bronze medal match on Saturday.
