Liga Portuguesa Abolicionista

Liga Portuguesa Abolicionista (English: "The Portuguese Abolitionist League"), was the Portuguese equivalent of the British Ladies National Association for the Repeal of the Contagious Diseases Acts.

It was established in 1926 with the purpose to repeal the so-called reglementation system, which required prostitute women to registration and regular medical examination to prevent sexually transmitted infections.

It was a sub-group of the Conselho Nacional das Mulheres Portuguesas. It worked against the sexual exploitation of women and children within the sex industry, and the sexual double standards that excused it. It was active until 1957.
