Prudente José de Morais Barros (; 4 October 1841 – 3 December 1902) was the third
President of Brazil. He is notable as the first civilian president of the country, the first to be elected by direct popular ballot under the permanent provisions of Brazil's
1891 Constitution, and the first to serve his term in its entirety. His presidency, which lasted from 15 November 1894 until 15 November 1898, was marked by the
War of Canudos, a
campesinant revolt in the northeast of the country that was crushed by the
Brazilian Army. He also had to face a break in diplomatic relations with
Portugal that was successfully mediated by Queen
Victoria of the United Kingdom.
