Encarnación López Júlvez, better known by her stage name, La Argentinita (Buenos Aires, March 3, 1898 – New York, September 24, 1945), was a Spanish-Argentine flamenco dancer, choreographer and singer.

Among her early performances was the 1920 premiere of Federico García Lorca's musical play El maleficio de la mariposa as "the Butterfly".

[4] She announced her retirement in 1926, but would quickly return to the show business as part of the artistic renewal that led her to the Generation of ‘27, in which she combined flamenco, tango, bulerías and boleros.

[6] Adapting pieces to popular tradition, she toured Europe, triumphing in Paris and Berlin and participating in the artistic movements of that time along with Spanish poets such as Rafael Alberti, Federico García Lorca, Edgar Neville and Ignacio Sánchez Mejías.

Among the ten songs were "Los cuatro muleros", "Zorongo gitano", "Anda Jaleo" and "En el Café de Chinitas".

López Júlvez staged several flamenco theatrical shows, including an adaption of Falla's El amor brujo (Love, the Magician) in 1933, and Las Calles de Cádiz (The Streets of Cadiz) in 1933 and 1940.

She sought refuge in her work and moved to Buenos Aires to dance at the Teatro Colón; from there she embarked on a long American tour.

In 1943, she presented the flamenco troupe El Café de Chinitas at the Metropolitan Opera House in New York, with her own choreography, texts by García Lorca, scenery by Salvador Dalí and the orchestra directed by José Iturbi.

On May 28, 1945, she gave her last performance at the Metropolitan of the orchestral work El Capricho Español, composed in 1887 by Nikolai Rimsky-Korsakov and based on Spanish melodies.

This display consisted of 17 original costumes that the dancers wore in some of their most notable performances, including "La cosecha" by Enrique Granados and "El Café de Chinitas" by Federico García Lorca.
