Aqua Anio Novus (Latin for "New Anio aqueduct") was an ancient Roman aqueduct supplying the city of Rome. Like the Aqua Claudia, it was begun by emperor Caligula in 38 AD[1] and completed in 52 AD by Claudius, who dedicated them both on August 1.

Together with the Aqua Anio Vetus, Aqua Marcia and Aqua Claudia, it is regarded as one of the "four great aqueducts of Rome."[2]
