Boris Fausto (São Paulo, 8 December 1930) is a Brazilian historian, political scientist and writer. During his career, he carried out studies on the political history of Brazil in the republican period, about mass immigration to Brazil, crime and criminality in São Paulo and authoritarian thinking. One of his main works is Revolução de 1930 - historiografia e história (The 1930 Revolution - historiography and history), first published in 1970, in which he confronts visions that defend the state of São Paulo during the 1930 revolution and the subsequent 1932 Constitutionalist Revolution.
