Agustín Arturo Prat Chacón (American Spanish: [aɾˈtuɾo pɾat t͡ʃaˈkon]; April 3, 1848 – May 21, 1879) was a Chilean lawyer and navy officer. He was killed in the Battle of Iquique, during the War of the Pacific. During his career, Prat had taken part in several naval engagements, including battles at Papudo (1865), and at the Abtao (1866). Following his death, his name became a rallying cry for Chilean forces, and Arturo Prat has since been considered a national hero.
