Ralph de Warneville (died 1191; sometimes Ralph de Varneville or Ralf of Wanneville) was the twentieth Lord Chancellor of England as well as later Bishop of Lisieux in Normandy. Ralph was probably from Varneville aux Grès in Normandy, from which he derived his name. Ralph also held offices in England. He was from 1167 until 1181, and was Archdeacon of the East Riding at about the same time. Ralph served King Henry II of England as Lord Chancellor from 1173 to 1181. Ralph died on 10 September 1191, as his death was commemorated on 10 September at St Evroul.
