Papianilla (floruit 455) was a Roman noblewoman.
She was the daughter of Eparchius Avitus, a member of the senatorial aristocracy of Gaul. Papianilla had two brothers, Agricola and Ecdicius, and possibly some sisters; she was related to another Papianilla (wife of the prefect Tonantius Ferreolus).
Before her father's rise to the throne (455), she married Sidonius Apollinaris, another member of the same aristocracy, and had four children: Apollinaris, Severiana, Roscia and Alcima.
Papianilla brought her husband the estate called Aviaticum[1] in Auvergne. Her husband gave away silver vessels from their home to the poor, but he criticised him and bought them back (Gregory of Tours, History of the Franks, II, 22).
