Ivory Coast’s President Alassane Ouattara has won a second five-year term with nearly 84% of the vote, electoral commission officials say.
His previous victory was rejected by the incumbent, Laurent Gbagbo, sparking a civil war which killed 3,000 people.
Mr Ouattara’s closest challenger, Pascal Affi N’Guessan, got 9%. He is an ally of Mr Gbagbo who faces trial at the International Criminal Court.
Several candidates withdrew from the poll, saying it was not free and fair.
However, on Monday US election observers said the election was credible.
Mr Ouattara required more than 50% of the vote to avoid a run-off.
The 55% turnout was sharply down compared to 80% in 2010.
The last elections sparked five months of violence when Mr Gbagbo refused to step down.
He is now in The Hague, where he is due to go on trial next month on war crimes charges, which he denies.
