Ega (also spelle Aega or Egua) was 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. On his death, at Clichy, Nanthild replaced him, a hardened opponent of the local Burgundian nobility, in Burgundy by a Frank and like opponent of the local power factions, Flaochad. The magnates elevated Erchinoald to his mayoralty in Neustria.
