Bifus
Bifus or Bisi was a medieval Bishop of the East Angles.
Bifus' consecration is normally dated to 669 or 670. However, there is reason to suspect the Venerable Bede made a mistake and he was actually consecrated in 664. He resigned the see in 672. He was the last bishop of the East Angles.
Bede in his history, records that he attended the Council of Hertford in 672. When he resigned, his bishopric was divided into the sees of Dunwich and Elmham.
