Arnulfi wa Soissons (pia: Arnoul, Arnulf, Arnold wa Oudenburg; Tiegern, leo nchini Ubelgiji, 1040 - alifariki 1087) alikuwa mkaapweke, halafu abati, padri na hatimaye askofu wa Soissons kuanzia mwaka 1080. Alipojitokeza mwingine kama askofu wa mji huo, aliona afadhali kurudi utawani badala ya kushindana naye. Hivyo akaanzisha monasteri. Papa Kalisti II alimtangaza kuwa mtakatifu tarehe 6 Januari 1120. Sikukuu yake ni tarehe 14 Agosti. Watakatifu wa Agano la Kale Orodha ya Watakatifu Wakristo Orodha ya Watakatifu wa Afrika Orodha ya Watakatifu Wafransisko Martyrologium Romanum H.
