At the 2017 Africa Cup of Nations in Gabon, Ondoa was again the undisputed goalkeeper for the "Indomitable Lions". He was man of the match in their quarter-final win over Senegal, in which he saved the decisive attempt from Sadio Mané in the penalty shootout. Cameroon won the title with a 2–1 victory over Egypt in the final, and he was elected into the Team of the Tournament.
