Osvaldo Roberto Suárez (17 March 1934 in Wilde – 16 February 2018)[1] was an Argentine long-distance runner who won four gold medals at the Pan American Games.

He was punished by the Revolución Libertadora (The Liberating Revolution) and blamed for receiving favors to travel (even being a famous and successful athlete), so he could not be at the 1956 Melbourne Olympic Games.

After that, he represented his native country at two Summer Olympics, in 1960 and 1964.

After retiring from his running career, he became a professional athletics coach.
