Bernard (died between 1047 and 1049) was the Bishop of Gaeta for fifty years from his appointment in 997 until his death. He was a member of the Docibilan dynasty which ruled the Duchy of Gaeta from 867 to 1032. During his long episcopate he achieved the economic security of his see in the face of labour difficulties, annexed the diocese of Traetto to his own in or soon after 999, and witnessed the decline and replacement of his family in Gaeta.
