Turibius of Astorga was a 5th-century bishop and archdeacon of Tui who served the early Church in Roman Spain. He is primarily recognized for his commitment to ecclesiastical discipline and his vigorous defense of Nicene Christianity against the Priscillianist heresy. During his career, he organized a local synod in 446, an effort that earned him written support from Pope Leo the Great. He spent his life in Astorga, where he eventually died in 460.
