Fergal mac Anmchada (died 802) was a King of Osraige in modern County Kilkenny.
He was of the dynasty that ruled over Osraige in the early Christian period known as the Dál Birn and was the son of Anmchad mac Con Cherca (died circa 761), a previous and aggressive king.
[1] The Osraige plunged into civil war upon the death of his father Anmchad.
With the accession of Fergal, the Osraige began a period of stability and direct father to brother or son succession in the 9th century.
