Guy I of Auvergne

Guy I of Auvergne was viscount of Auvergne in the later tenth century and the first to rule it as count. He became viscount after his brother Robert III. After Count William Tête d'Étoupe died around 963, the viscounts filled the vacant county, and by the 980s charters styled Guy count.

He married Ausenda. In 985 he attacked Mende in Gévaudan; a later bishop's account claims he was killed by a lance before the city gates. He died around 989 and his brother William IV succeeded him.
