African dramatist and short-story writer, one of bilingual Cameroon's few writers to achieve success both in French and in English. Oyono-Mbia attended the Collège Évangélique at Limbamba and then went to England, graduating from the University of Keele in 1968. With skills often compared to those of Molière, Oyono-Mbia exercised an unusual ability to create comedies that play well both on stage and on radio. Among them are Trois prétendants . . . un mari (1962; Three Suitors . . . One Husband), Until Further Notice (1967), Notre fille ne se mariera pas! (1969; “Our Daughter Will Not Marry!”), and His Excellency's Train (1969), all written on his favourite theme of youth versus adult, modernity versus tradition.

In the 1970s his penchant for satire was also evident in three volumes of amusing tales of life in his native village, Chroniques de Mvoutessi (1971–72; “Chronicles of Mvoutessi”). From 1969 Oyono-Mbia was professor of literature at the University of Yaoundé in Cameroon. Between 1972 and 1975 he was chief administrative officer in the Office of Cultural Affairs in the Ministry of Information and Culture.
