The Posthumous Memoirs of Brás Cubas, also translated as Epitaph of a Small Winner, is a novel by Brazilian writer Joaquim Maria Machado de Assis. The book presents the memoir of its protagonist, Brás Cubas, as told from beyond the grave.

The novel has a unique style of short, erratic chapters that shift in tone and style. Instead of the clear and logical construction of a typical nineteenth-century realist novel, it uses surreal devices of metaphor and playful narrative construction.
