Alda Soares de Melo Cardoso dos Santos Victor (born 1921 or 1922) was one of the so-called "Magnificent Five" Portuguese women who were elected in December 1976 as municipal mayors in the first election for mayors in Portugal after the April 1974 Carnation Revolution.
She married a magistrate in 1940 and travelled around the country, accompanying him on his various postings for 14 years before moving to the Portuguese capital of Lisbon.
Their preference was apparently for her husband, who came from the village of Soza in the municipality, but as he had had connections with the Estado Novo regime that had been overthrown by the Carnation Revolution, he was barred from being a candidate.
She campaigned very little, had no experience of public speaking and was at home in Lisbon when she found out that she had been elected.
In addition to her the others were Judite Mendes de Abreu, Francelina Chambel, Lurdes Breu, and Odete Isabel.
