William of Norwich (c. 1132 – March 22, 1144) was an English boy whose death was, at the time, attributed to the Jewish community of Norwich. It is the first known medieval accusation of ritual murder against Jews.
William was an apprentice tanner who regularly came into contact with Jews and visited their homes as part of his trade. His death was unsolved; the local community of Norwich attributed the boy's death to the Jews, though the local court would not convict them for lack of proof. William was shortly thereafter acclaimed as a saint in Norwich, with miracles attributed to him.
William's story was told in The Life and Miracles of William of Norwich, a multi-volume Latin work by Thomas of Monmouth, a monk in the Norwich Benedictine monastery. Thomas started The Life in 1149/50; he completed volume 7 by 1173. Jessop, one of the editors of Thomas' work, describes Thomas as belonging to the class of those who are "deceivers and being deceived."
