Agustina Raimunda Maria Saragossa i Domènech or Agustina of Aragón (March 4, 1786 – May 29, 1857) was a Spanish heroine who defended Spain during the Peninsular War, first as a civilian and later as a professional officer in the Spanish Army.
Known as "the Spanish Joan of Arc," she has been the subject of much folklore, mythology, and artwork, including sketches by Francisco Goya and the poetry of Lord Byron.
