Patricio Nazario Yáñez Candia (born January 20, 1961) is a Chilean former footballer who played as a forward.

He moved to Spain to play for Real Valladolid, and won the Copa de la Liga in 1984.

[1] He made his debut on June 13, 1979, in a friendly against Ecuador, replacing Jorge Neumann, and had his last match on November 16, 1994, against Argentina.

[2] In 1989, during the infamous incident involving the goalkeeper Roberto Rojas in a match against Brazil, Yáñez, under the frustration of believing his team was subject to unfairness, performed a gesture to the Brazilian fans by holding his genitals with both of his hands and his middle body slightly bent towards the front in an act of sexual intercourse.

The moment was captured by Chilean national television, and as years have passed, the offensive gesture, when repeated or remembered, is known as "Pato Yáñez".
