Vasco Maria Nunes Barata de Sousa Uva (born 15 December 1982 in Lisbon) is a former Portuguese rugby union player.
He took his law degree at the Catholic University of Portugal, in Lisbon, and he works as a lawyer.
He was the captain of the Portugal national team in three of the four games at the 2007 Rugby World Cup finals.
He was replaced as the capitan of the "Lobos" by João Correia before the match played with Russia, at 1 March 2008, which resulted in a 26–41 loss.
After the RWC he co-wrote Hoje é por Portugal (2007) (Today is For Portugal), a title taken from his quote before the first game against Scotland, a book that relates everything that this amateur team, and himself as the captain, lived before the qualifications and during this major sportive and professional event of their lives.
