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
Roman emperor from AD 305 to 311; although he was probably not a direct descendant of the earlier family.
The only surnames associated with the early Galerii are Fundanus and Trachalus, but it is not known whether they were personal cognomina, or whether they instead represented distinct families within the gens.
