Aega (also spelled Ega or Egua) is the mayor of the palace and regent, alongside the queen mother Nanthild, of Neustria and Burgundy from 639, on the death of Dagobert I, to his death in 641, during the reign of the minor Clovis II.

He is a hardened opponent of the local Burgundian nobility.

On his death, at Clichy, Nanthild replaces him in Burgundy by Flaochad, a Frank and like opponent of the local power factions.

The magnates elevate Erchinoald to his mayoralty in Neustria.
