UMAR, an acronym which stands for Alternative and Answer Women's Union in Portuguese (União de Mulheres Alternativa e Resposta), is a Portuguese women's rights organization founded in 1976. From 1976 to 1989, the acronym originally stood for Antifascist and Revolutionary Women's Union (União de Mulheres Antifascistas e Revolucionárias). In 1989, the organization changed its name to Movement for the Social Emancipation of the Portuguese Women (Movimento para a Emancipação Social das Mulheres Portuguesas) and again, in 1999, to the name it currently holds.
