The gens Galeria was a Roman family of Imperial times. The family first rose to prominence under the Julio-Claudian dynasty, but the most illustrious person of the name was Galerius, one of the heirs of Diocletian, and Roman emperor from AD 305 to 311; although he was probably not a direct descendant of the earlier family.
