Agnellus (487 – 1 August 570) was a bishop of Ravenna in the Praetorian prefecture of Italy from 557 to his death.
The main source about him is by Liber Pontificalis Ecclesiae Ravennatis by Andreas Agnellus.
[1] Agnellus was probably born in 487, based on the estimation of his age at the time of death.
He was apparently born to a prominent family of Italian nobles, as he is recorded inheriting great wealth.
He was consecrated a deacon by Ecclesius of Ravenna (term 521–532).
