Sara Facio (18 April 1932 – 18 June 2024) was an Argentine photojournalist and publisher. She was best known for having photographed, along with Alicia D'Amico, various cultural personalities, including Argentine writers Julio Cortázar, María Elena Walsh and Alejandra Pizarnik. She co-founded the publishing house "La Azotea" alongside María Cristina Orive in 1973.

Facio was instrumental in establishing a publishing house for photographic work in Latin America and for the creation of a prominent photographic exhibition space in Argentina.

Facio began working as an assistant to Annemarie Heinrich and started taking her own photographs in 1957.

In 1960, Facio and Alicia D'Amico opened a photography studio together. Facio co-founded La Azotea with María Cristina Orive in 1973. La Azotea was the first publishing house printing photo books in Latin America.

Following the 1978 "Latin American Colloquiums of Photography" held in Mexico City, Facio worked with fellow artists to co-found the Argentine Photography Council [es] (Spanish: Consejo Argentino de Fotografía).

In 1985, Facio established the Fotogalería of the Teatro Municipal General San Martín, which has become one of the most prominent photographic exhibition spaces in Argentina. Facio served as the director of the gallery until 1998.

"What I do in photography is to ensure that the day I die they do not say that a cow died but that a person who saw that died. And what I saw is in my photos. As if to say, 'This is my city, my people, the one I admire, the one I like.' That is my canon."

One of her most notable works of photojournalism was her coverage of Peronism in Argentina during the 1970s. She was noted for photographing marchers and protesters at Plaza de Mayo in Buenos Aires, which was different as most photojournalists focused their works through aerial views of Casa Rosada. During her career, she was also known for photographing Jorge Luis Borges, Julio Cortázar, Astor Piazzolla, Pablo Neruda, Gabriel García Márquez and Mario Vargas Llosa.
