Davida – Prostituição, Direitos Civis, Saúde (Prostitution, Civil Rights, Health) is an NGO that supports sex workers in Brazil. It was founded in 1992, is based in Rio de Janeiro, and gained international notoriety in 2005 when it launched the fashion line Daspu.

Davida works in HIV/AIDS prevention and tries to improve the working conditions and the legal and societal status of prostitutes in Brazil. Its main aim is to end the discrimination of prostitutes and the recognition of prostitution as a regular profession. Prostitution itself is not illegal in Brazil, but employing prostitutes is.

The organization was founded in 1992 by retired prostitute Gabriela Silva Leite, who holds a degree in sociology, and her partner Flavio Lenz. In 1978 she had already organized a demonstration in São Paulo against police brutality, because of the murder of a prostitute friend. In 1987 she organized the first prostitution congress, a meeting of Brazilian prostitutes to create a network of sex worker initiatives.
