Fidelio Ponce de León (24 January 1895[1] - 19 February 1949[2]) was the pseudonym of Alfredo Fuentes Pons, a Cuban painter.

Along with Antonio Gattorno, Victor Manuel, Amelia Peláez, and Wifredo Lam, he is considered part of the "Vanguardia" movement in Cuban art; however, unlike many of his contemporaries he never studied in Europe, and so had comparatively little contact with European modernism.

Nevertheless, he listed among his influences Amedeo Modigliani, along with El Greco, Rembrandt, and Bartolomé Esteban Murillo.

Later in life Ponce de León contracted tuberculosis; he died in Havana on 19 February 1949.

[3] His paintings such as La Familia ("The Family") and Niños ("Children", 1938), reflect Cuban society of the 1930s, and offer a contrasting view to the idealized vision seen in the art of some of the other artists.
