Dyfodwg or Tyfodwg was a 6th-century Welsh saint. He is one of the three saints (with Illtyd and Gwynno) from whom the ancient parish of Llantrisant takes its name and possibly the patron (believed to have been Tyfodwg son of Gwilfyw) of the parish church of Llandyfodwg in Glynogwr between Blackmill and Gilfach Goch in Bridgend Wales.Some say he was a Breton monk a disciple of Saint Illtyd of Llantwit Major.
