Roque José Antonio del Sagrado Corazón de Jesús Sáenz Peña Lahitte (19 March 1851 – 9 August 1914) was an Argentine politician and lawyer who served as President of Argentina from 12 October 1910 to his death in office on 9 August 1914. He was the son of former president Luis Sáenz Peña. He was a candidate for an internal, modernist line within the National Autonomist Party. He was responsible for passing Law 8871, known as "Sáenz Peña Law", which greatly reformed the Argentine electoral system, making the vote secret, universal and compulsory for males over 18. This effectively ended the rule by electoral fraud of the conservative Argentine oligarchy, the Generation of '80, and paved the way for the rise of the Radical Civic Union in the first free elections of the country.
