Wilson Costa de Mendonça (born 3 October 1956), simply known as Wilsinho, is a Brazilian former professional footballer who played as a right winger.
Revealed by Vasco da Gama's youth sectors, Wilsinho played most of his career at the club, where he was state champion in 1977 and vice-Brazilian in 1979. He also played for Flamengo and Fluminense, where he was champion of the 1984 Campeonato Brasileiro Série A. He ended his career at Recreativo Huelva in Spain in 1989. He received the nickname "Xodó da Vovó", in reference to the Brazilian title of the Precious Pupp cartoon, since, like the dog in the work, he always saved Vasco da Gama.
