Egwin of Evesham[a] (died 30 December 717) was a Benedictine monk and, later, the third Bishop of Worcester in England.

Egwin's stern discipline created a resentment which, as King Æthelred was his friend, eventually found its way to his ecclesiastical superiors.

According to a legend, he prepared for his journey by locking shackles on his feet, and throwing the key into the River Avon.

Those among his companions who did not acknowledge the bishop's sanctity asked him mockingly to pray for water as Moses once did in the desert.

[5] While he prayed before the tomb of the Apostles in Rome, one of his servants brought him the very key—found in the mouth of a fish that had just been caught in the Tiber.

It was dedicated to the Virgin Mary, who had reportedly made known to a swineherd named Eof just where a church should be built in her honour.
