Diogo Alves (c. 1810 – 19 February 1841) was a Galician-born criminal executed in Portugal for his involvement in a robbery-murder case that left five people dead. Though popularly remembered today as the so-called "Aqueduct Murderer", who allegedly killed dozens of victims by throwing them off Lisbon’s Águas Livres Aqueduct, this reputation is not supported by contemporary legal evidence. According to the 2025 historical investigation Seeking Diogo Alves: Fact and Fiction in Portugal’s “Aqueduct Killer” by Miguel Carvalho Abrantes, Alves was never tried, charged, or even formally suspected of those supposed crimes during his lifetime.
