Héctor Casimiro Yazalde (29 May 1946 – 18 June 1997) was an Argentine footballer who played as a striker.
Nicknamed Chirola, Yazalde scored 46 goals in one single season with Sporting Clube de Portugal, being awarded that season's European Golden Shoe.
Born in Avellaneda, Buenos Aires Province, Yazalde's beginnings in football were hazardous; he was visiting a friend who played with Piraña, an amateur club in the Argentine capital. He asked to join in the training session, immediately causing a stirring impression and signing the very day. From there, he signed with Club Atlético Independiente, going on to help the side win two national championships.
In 1971–72, Yazalde signed with Sporting Clube de Portugal, helping the Portugal outfit to the 1974 league title, during which he scored 46 goals in just 29 games, both a domestic and European record, and the 1973 Portuguese Cup. The following campaign, with the Lions finishing third, he netted 30, league's best and Europe's second.
As a prize for the European Golden Shoe, he received a Toyota car, which he sold, then sharing the money with his teammates. After his Portuguese spell, Yazalde successively represented Olympique de Marseille, Newell's Old Boys and Club Atlético Huracán, retiring in 1981 and becoming a player's agent, in Argentina.
Internationally, Yazalde played 10 times for his country, appearing at the 1974 FIFA World Cup, where he scored twice in three matches (both against Haiti, 4–1 win).
Yazalde died in Buenos Aires in June 1997, from hemorrhage and heart failure. He was aged 51.
