The Domus Augustana is the modern name given to the central residential part of the vast Roman Palace of Domitian (92 AD) on the Palatine Hill. In antiquity the name may have applied to the whole of the palace.
Its name is not directly related to the emperor Augustus (r. 27 BC – AD 14) and should not be confused with the nearby Domus Augusti, but probably refers to the later Roman meaning of Augustus as "emperor".
