Aufidia or Alfidia (flourished 1st century BC) was a woman of Ancient Rome. She was a daughter to Roman Magistrate Marcus Aufidius Lurco and an unknown mother. She was a member of the gens Aufidia, a Roman family of Plebs status which appeared in the Roman Republic and Roman Empire, and became a family of consular rank. Her father originally came from Fundi (modern Fondi, Italy).
She married the future praetor, Marcus Livius Drusus Claudianus. They had at least one child: a daughter Livia Drusilla (58 BC-29). Her husband also adopted Marcus Livius Drusus Libo, who served as a Roman consul. Livia was to become the first Roman Empress and third wife of the first Roman Emperor Augustus. Aufidia would be the maternal grandmother to Roman emperor Tiberius Claudius Nero and Roman General Nero Claudius Drusus. The Roman emperors Caligula, Claudius and Nero were her direct descendants.
The gens Aufidia was a plebeian family at Rome, which is not known until the later times of the Republic. The first member to obtain the consulship was Gnaeus Aufidius Orestes, in 71 BC.
