Agustin Cardenas Alfonso (April 10, 1927, Matanzas, Cuba - February 9, 2001, Havana, Cuba) was a Cuban sculptor who was active in the Surrealist movement in Paris. His sculptures were influenced by Brancusi, Henry Moore, and Jean Arp. Poet Andre Breton said of his artistic hand that it was "efficient as a dragonfly."

Cardenas was a descendant of slaves from Senegal and the Congo, and was born in Matanzas, a major port in the sugar industry. In Cuba, Cardenas studied under Juan Jose Sicre, and from 1943 to 1949 at Escuela Nacional de Bellas Artes "San Alejandro" in Havana. He was member of Asociacion de Grabadores de Cuba (AGC) from 1951 to 1955, and of the creative group Los Once from 1953 to 1955. Cardenas' work was exhibited several times: in 1952, "Pintura Avila Escultura Cardenas" at Palacio de los Trabajadores in Havana, and in 1955 a selection of pieces in "Agustin Cardenas: 20 esculturas" at the Museo Nacional de Bellas Artes de La Habana.

He settled in Paris in 1955 and in 1957 integrated himself in the Surrealist movement there. His work incorporated aspects of his African heritage and of Dogon totems.

In 1987, his work in was in the Corea Gallery, Seoul, South Korea. In 1993, his work was exhibited in "Agustin Cardenas" in the Museo Nacional de Bellas Artes de La Habana and in 2002, Cardenas' work was presented in "Desires and Grace" at the Haim Chanin Fine Arts Gallery in New York City.
