John Wessington (also Washington) (died 1451) was an English Benedictine who became prior of Durham Abbey.
He retained this office for twenty-nine and a half years, during which he was active in extending and repairing the buildings of the cathedral and its dependent houses.
He resigned his priory in May 1446, the bishop of Durham Robert Neville, issuing letters for the election of his successor on the 26th.
The chapter of Durham made provision for his old age: he was assigned a pension, a private room in the monastery, and five attendants.
Edward Bernard gives a list of Wessington's works extant among the manuscripts at Durham Cathedral; they include treatises His ‘Defensio Jurium, Libertatum, et Possessionum Ecclesiæ Dunelmensis adversus Malitias et Machinationes ipsa molentium impugnare’ extant in Cottonian MS. Vitellius A xix, was damaged by fire, but was partially restored.
