This purpose of this work is to know if Brazilian black women experienced a different treatment within prison as a consequence of their race. During the last four years is possible to observe an expressive growth of crimes committed by women in Brazil, which calls for the attention of the experts on the subject. Futhermore, the Brazilian prisional system keeps structural deficiencies which reinforce the institutional culture of violence by promoting discriminatory practices and approaches that hurt the dignity and violate the rights. These practices also occur within female prisions, and our hypothesis is that they can be better observed from a ethnical and racial point of view. This reality reveals another face of social inequality and racism that can accentuate becoming criminal and vulnerabilities to the commission of a crime. In this context, the present work discuss the expressions of racism within the prisional system. The study relied on the contribution of ten women who are, or were, under the prisional system of Rio de Janeiro. The work shows that the black population of the state of Rio de Janeiro is more represented in prisons than in the general population of the state. Eventhough, the interviewed women did not recognize racism expressions within the prisons.
