Leopoldo Ruiz (7 August 1926 – 10 May 1986)[1] is an Argentine professional golfer.

During his career, Ruiz won the Argentine Professional Ranking four times, and competed in seven major championships, appearing five times in The Open Championship, from 1958 to 1961 and 1968, and twice in the Masters Tournament in 1962 and 1965.

In 1958, he missed out on being in a playoff for the Open title, when he had a triple bogey at the last hole at Royal Lytham & St Annes to finish tied for 5th place, three strokes off the leaders.

Ruiz represented Argentina in the World Cup on eight occasions between 1957 and 1969, and was runner up in the team competition alongside Roberto De Vicenzo in 1964.

Note: Ruiz never played in the U.S. Open nor the PGA Championship.
