Dymphna (also Dimpna, Dymfna, Dimfna, Dympna and Dympha, Irish also Damhnait or Davnet) is a saint honoured in Catholic and Eastern Orthodox traditions. According to tradition, she lived in the 7th century and was martyred by her father. The life of Dymphna was first recorded in the 13th century by a canon of the Church of Aubert of Avranches at Cambrai, France. It was commissioned by Guiard of Laon, the Bishop of Cambrai (1238–1248).
