Audefroi le Bastart (modern French Bâtard) was a French trouvère from Artois, who flourished in the early thirteenth century. Of his life nothing is known, though he is certainly the illegitimate child of a noble or upper-class bourgeouise family, but his family is not to be identified with the noble family Arras or with the bourgeouise family of Louchart, also from Arras; Audefroi himself is not to be identified with Gautier d'Arras. The , to whom some of his songs are addressed, is probably the Châtelain of Bruges who joined the Fourth Crusade.
