No. Nigeria was never a French colony. It was a British colony and protectorate from the late 19th century until independence on 1 October 1960.
France colonized Niger, Chad, Cameroon (part), Benin (Dahomey), Burkina Faso (Upper Volta), Mali (French Sudan), Mauritania, Senegal, Guinea, Ivory Coast, Togo (League mandate), Central African Republic, Congo, Gabon—all bordering or near Nigeria.
The linguistic legacy: Nigeria is Anglophone (official language English); its neighbors are largely Francophone.
