Guigues V of Forez

Guigues V (died 12 September 1259) was count of Forez from 1241, the elder son of Count Guigues IV and Matilda of Courtenay. Succeeding while still a boy, he faced the claims of his uncle William, lord of Baffie, until a treaty of 1244 confirmed him in possession of the county.

He married Alix de Chacenay, but the marriage produced no children. On his death the county passed to his younger brother, Renaud I.
