Maximin of Trier was the sixth bishop of Trier, serving from roughly 332 until his death in 346. Born near Poitiers, he was a notable opponent of Arianism and maintained close ties to the imperial courts of Constans and Constantine II. During the Arian controversy, he famously refused to host four Arian bishops who traveled to Trier to influence Emperor Constans. He is also remembered for providing refuge to Athanasius of Alexandria on two separate occasions during the latter's periods of exile.
