Domitia Longina (c. AD 53-55–c. AD 126-130) was an Empress of Rome and wife to the Roman Emperor Domitian. She was the youngest daughter of the general and consul Gnaeus Domitius Corbulo. Domitia divorced her first husband Lucius Aelius Lamia in order to marry Domitian in 71. The marriage produced only one son, whose early death is believed to have been the cause of temporary rift between Domitia and her husband in 83.
