William VIII, Count of Auvergne

William VIII, called the Old (c. 1100–1182), was count of Auvergne, a son of Count William VI and brother of Robert III. In 1155, after a long quarrel with his nephew William VII the Young, he seized part of the county and ruled from Clermont.

Louis VII imprisoned both claimants briefly and freed them in 1164. When Henry II arbitrated in 1167, William VIII refused his judgment and did homage to Louis VII instead, while his nephew paid homage to Henry. He married Anne of Nevers and died in 1182, leaving the county to his son Robert IV.
