Juan Carlos Copes (31 May 1931 – 16 January 2021) was an Argentine tango dancer, choreographer, and performer.

Copes and Nieves starred in a 1962 production at the Alvin Theatre on Broadway as well as appearing on numerous episodes of The Ed Sullivan Show from 1962 to 1964.

[9] The reintroduction of democracy to Argentina led to a renaissance in Argentine Tango in which Copes and Nieves were leading figures.

[10] Copes taught the style, which was later known as the "estilo Copes-Nieves," to many dancers and his pupils included Robert Duvall, Julio Bocca, Eleonora Cassano, Mikhail Baryshnikov and Liza Minnelli.

[1] Copes had a daughter, Johana, with his second wife, Myriam Albuernez (who was 20 years his junior) in 1976, and he began to dance with her on stage in 1994.

[9] His credits included chief choreographer of Ástor Piazzolla's María de Buenos Aires (1968).
