Valeria Sarmiento (born 29 October 1948) is a film editor, director and screenwriter best known for her work in France, Portugal and her native Chile.

She is the widow of Chilean film director Raúl Ruiz (1941-2011) with whom she collaborated for decades as regular editor and co-writer.

Sarmiento was born in the Chilean municipality of Valparaíso and was first exposed to film at the age of five, becoming familiar with the work of Orson Welles, Alfred Hitchcock and others.

[1] She rarely saw French films due to censorship but, thanks to what she refers to as a "moment of magic", was able to watch Jean-Luc Godard's Breathless (1960) at the age of twelve.

[1] Sarmiento made her directorial debut with the documentary Un sueño como de colores (1972) about a group of Chilean women dedicated to striptease.
