The Headless Woman (Spanish: La mujer sin cabeza / La mujer rubia) is a 2008 Argentine psychological thriller art film written and directed by Lucrecia Martel and starring María Onetto. The plot revolves around Vero (short for Verónica) (Onetto), who hits something while driving on a deserted road near Salta. Not being sure if she has hit a person or an animal, she drives off, and becomes increasingly mentally disturbed.

The film premiered in competition at the 2008 Cannes Film Festival on May 21, 2008. It opened nationwide on August 21, 2008, after being screened at the Locarno International Film Festival earlier that month. While The Headless Woman was mostly lauded by critics for its cinematography and social commentary, others were critical towards the film's slow pace and lack of clear narrative. In 2016, the film was ranked No. 89th on BBC's list of the 100 greatest films of the 21st century. In 2022, it was selected as the 24th greatest film of Argentine cinema in a poll organized in 2022 by the specialized magazines La vida útil, Taipei and La tierra quema, which was presented at the Mar del Plata International Film Festival.
