Ebalus or Ebles Manzer or Manser (c. 870 – 935) is Count of Poitou and Duke of Aquitaine on two occasions: from 890 to 892 and from 902 (Poitou) and 927 (Aquitaine) to his death.

Ebles is an illegitimate son of Ranulf II of Aquitaine.

"Manzer" or "Mamzer" is a Jewish word that means bastard, son of a Christian man and Jewish woman.

It appears that Ebles did not mind his name.
