Maeonius (d. 266/267), or Maconius, was a short-lived Roman usurper.

|Emperor of the Palmyrene Empire|
|House||House of Odaenathus|
He was the nephew (according to Zonaras xii.24) or the cousin (according to Historia Augusta, which lists him among the Thirty Tyrants) of Odaenathus of Palmyra, who had taken control of the Eastern provinces after the defeat and capture of Emperor Valerian by Shapur I of the Sassanid Empire.
According to Historia Augusta, Maeonius killed Odaenathus and his son Hairan during a celebration, because of a conspiracy organized by Zenobia, wife of Odaenathus, who wanted her sons to succeed her husband instead of Hairan (who was the son of Odaenathus by another woman). According to Gibbon, the murder was revenge for a short confinement imposed on Maeonius by Odaenathus for being unrespectful.
Zonaras tells that Maeonius was killed immediately after the murder of Odaenathus, while Historia has Maeonius proclaiming himself emperor, with Zenobia having had him soon killed, in order to take the power for herself.
