List of counts of Albon and dauphins of Viennois

The counts of Albon (French: comtes d'Albon) were members of the medieval nobility in what is now south-eastern France.

Guigues IV, Count of Albon (d. 1142) was nicknamed le Dauphin or 'the Dolphin'.

By 1293, the lands ruled by the Counts Albon, the old comitatus Albionis, were known as the Dauphiné of Viennois (Latin: Dalphinatus Viennensis).

When the king of France had no son, he would personally rule the Dauphiny separately, as dauphin.

Humbert II sold his lands and titles to Philip VI of France.
