is the tritagonist of the 2005 neo-Western crime thriller novel No Country for Old Men and its 2007 film adaptation.

She's the loyal young wife of protagonist Llewelyn Moss, who finds himself hunted by the psychopathic hitman Anton Chigurh after taking money from a botched drug deal; Llewelyn is later killed on the run.

In her final scene, she refuses to participate in Anton's coin-toss game of chance to bet her life, arguing that he is acting out of free will instead of enforcing fate.
