Sylvain Alex Ovono (born 26 March 1976) is a retired Cameroonian footballer, who played as a forward.
Born in Yaoundé, Ovono began playing football in Europe in Turkey, starting with modest Sivasspor, then switching to the Süper Lig in the 1997–98 season, appearing very rarely for the last-placed team, Belediye Vanspor.
In the following decade, almost uninterrupted, he played in Portugal, mostly in the lower leagues. The best he achieved was appearing two seasons in the second division for Associação Naval 1º de Maio (only 12 matches over the course of two seasons combined). After a very brief spell in Greece, he resumed his career in the country, appearing for seven different clubs (notably Portimonense SC, when it was in the third level).
In 2001, Ovono had an unsuccessful trial at 1. FC Union Berlin in Germany.[2] After returning to Portugal, he eventually retired at the age of 33, his last club being Grupo Desportivo Sourense in Soure.
