Arnulfo wa Metz (Lay-Saint-Christophe, leo nchini Ufaransa, 582 hivi - Remiremont, 645 hivi) alikuwa mwanasiasa mwenye cheo kikubwa ikulu ya Austrasia. Baba wa watoto wawili maarufu, alichaguliwa kuwa askofu wa Metz akashughulikia uchungaji bila kuacha majukumu ya kisiasa. Hatimaye aliruhusiwa na mfalme kwenda kwa siri kuishi kama mmonaki karibu na monasteri ya Hamend iliyoanzishwa na rafiki yake Amato. Tangu kale anaheshimiwa na Wakatoliki na Waorthodoksi kama mtakatifu. Sikukuu yake huadhimishwa tarehe 18 Julai.
