John of Wallingford (died 1258) was a Benedictine monk at the Abbey of St Albans, who served as the abbey's infirmarer at some time between c.1246-7 and his death in 1258. He is now mostly known through a manuscript containing a miscellaneous collection of material, mostly written up by Wallingford from various works by his contemporary at the abbey Matthew Paris, which survives as British Library Cotton MS Julius D VII. This manuscript includes the so-called Chronica Joannis Wallingford or Chronicle of John of Wallingford.
