Malcolm IV (Mediaeval Gaelic: Máel Coluim mac Eanric; Modern Gaelic: Maol Chaluim mac Eanraig), nicknamed Virgo, "the Maiden" (between 23 April and 24 May 1141 – 9 December 1165), King of Scots, was the eldest son of Henry, Earl of Huntingdon and Northumbria (died 1152) and Ada de Warenne. The original Malcolm Canmore, a name now associated with his great-grandfather Malcolm III (Máel Coluim mac Donnchada), he succeeded his grandfather David I, and shared David's Anglo-Norman tastes.
Called Malcolm the Maiden by later chroniclers, a name which may incorrectly suggest weakness or effeminacy to modern readers, he was noted for his religious zeal and interest in knighthood and warfare. For much of his reign he was in poor health and died unmarried at the age of twenty-four.
