Félix Balyu (5 August 1891 – 15 January 1971) was a Belgian association football player who played for Club Brugge and the Belgium national football team.
Balyu was named to the Belgium squad for the 1920 Olympic Football Tournament, which Belgium hosted.[1] He made his sole appearance for his country in Belgium's first match, a 3–1 second-round[2] victory over Spain. Balyu played poorly and would not see the pitch for the remainder of the tournament.[3] Although Balyu did not play for Belgium again, he collected a gold medal as Belgium defeated Netherlands in the semifinals and Czechoslovakia in a controversial final match.
