Guigues IV.

Guigues IV (died 28 June 1142), called le Dauphin (Latin: Guigo Dalphinus), was the count of Albon from 1133. He was the first to take the name Dauphin, meaning "dolphin", which became a title among his successors.

Guigues was the eldest son and heir of Guigues III of Albon and Matilda. He was first called dauphin in a document of his father's from 1110. Another theory posits that Matilda was a daughter of Count Roger I of Sicily and the widow of King Conrad II of Italy.

Guigues had good relations with the priory of Oulx and the abbey of Bonnevaux, to which he made gifts. In 1140, however, Guigues was involved in a dispute with the bishop Hugh II of Grenoble. He was succeeded by his son Guigues V.

Guigues IV may have been the inspiration for the character of Schionatulander in Wolfram von Eschenbach's romance Titurel, written around 1217.
