Saint Peter's Fair is a medieval mystery novel by Ellis Peters, set in July – September 1139. It is the fourth novel in The Cadfael Chronicles, first published in 1981 (1981 in literature). The story occurs during The Anarchy, in the English town of Shrewsbury. It was adapted for television in 1997 by Central for ITV. The book was received positively, saying that Cadfael was "stylishly authentic, though not quite as darkly inventive, as his previous three [novels]". Another review considered that while "Murder abounds in these early chronicles", the "predictable plotting is amply compensated for by the author's wonderful re-creation of the period".
