Juraj Beneš (born March 2, 1940 in Trnava, died October 1, 2004 in Bratislava) was a Slovak composer, teacher, and pianist.

He graduated from the university called Academy of Music and Dramatic Arts (Vysoká škola muzických umení) in Bratislava and was a pupil of Ján Cikker , who was one of the best known Slovak composers. Since 1983 Beneš taught at the same university.

Beneš's work followed current trends and spanned genres. He was best in composing operas such as Cisárove nové šaty (The Emperor's New Clothes), Skamenený (Petrified), and Hostina (Feast) and often employed the human voice together with unusual instrument combinations as in Tri ženské zbory (Three Women's Choir).
