Sigfrith (also Sigfrid) (died 689) was abbot of Monkwearmouth Priory in Sunderland north-east England.
[1] Sigfrith was a deacon at the time he was chosen "by Ceolfrid [abbot of the twin abbey at Jarrow] and the monks" (Bede, Lives of the abbots, 10 - 13).
Bede states: Soon afterwards, both he and the abbey's founder Benedict Biscop both fell fatally ill: Two months later Sigfrid died, only four months before Benedict's own death.
