The Breviary of Alaric is a collection of Roman law, compiled by Roman jurists and issued by referendary Anianus on the order of Alaric II, King of the Visigoths, with the approval of his bishops and nobles. It was promulgated on 2 February 506, the 22nd year of his reign. It applied, not to the Visigothic nobles who lived under their own law, which had been formulated by Euric, but to the Hispano-Roman and Gallo-Roman population, living under Visigoth rule south of the Loire and, in Book 16, to the members of the trinitarian Catholic Church; the Visigoths were Arian and maintained their own clergy.

Alaric II was the King of the Visigoths from 484 until 507. He succeeded his father Euric as king of the Visigoths in Toulouse on 28 December 484; he was the great-grandson of the more famous Alaric I, who sacked Rome in 410. He established his capital at Aire-sur-l'Adour in Aquitaine. His dominions included not only the majority of Hispania but also Gallia Aquitania and the greater part of an as-yet undivided Gallia Narbonensis.
