Froila Arias (flourished 1056–72) was a Galician count who governed the fortress of Traba and the region of Trastámara during a tumultuous period. Froila was the son of Arias Tedóniz (flourished 1044–47), related apparently to the family of Rudesind, founder of the monastery of Celanova, with which Froila was connected as early a 1056. Froila was married to Ardio Díaz. As her dowry, she brought him the tenancy of Aranga. They had a daughter, Urraca Fróilaz, who married Count Pedro Fróilaz de Traba. The tenancies of Traba and Trastámara passed to Pedro after Froila's death. Froila may have had another daughter who was the mother of Arias Pérez.
