Osbern of Canterbury
Osbern (c. 1050 – c. 1090) was a Benedictine monk, hagiographer and musician, precentor of Christ Church, Canterbury. He is sometimes confused with Osbert de Clare, alias Osbern de Westminster. He is known as "the monk Osbern" or just "Monk Osbern".
He was born at Canterbury and brought up by Godric, who was dean from 1058–1080. He became a monk, and later precentor of Christ Church, and was ordained by Archbishop Lanfranc of Canterbury (d. 1089). He died probably between 1088 and 1093.
He was very skilful in music and is said to have written two treatises De re musica and De vocum consonantiis. 
- Vita S. Alphegi et de translatione S. Alphegi ("Life and Translation of St Ælfheah"), in prose. It was written at Lanfranc's request, about 1080 when there arose some dispute concerning Ælfheah's sanctity. See the remarks in William of Malmesbury's Gesta Pontificum.

- Vita S. Odonis archiepiscopi Cantuariensis. From William of Malmesbury's Gesta pontificum Anglorum we learn that Osbern wrote a life of Odo, but the work has now perished.
- (Henry Wharton, in his Anglia Sacra (London, 1691), 75–87, published a life of St. Bregwin which was wrongly attributed to Osbern).
- In addition, two letters which he wrote to Anselm abbot of Bec, probably about 1093, are preserved.
