Jermano I wa Konstantinopoli (Konstantinopoli, leo nchini Uturuki, 634 hivi - Platanion, 732 hivi) alikuwa Patriarki wa mji huo kuanzia mwaka 715 hadi 730 alipolazimishwa na kaisari Leo III kujiuzulu na kwenda uhamishoni kwa kutetea heshima kwa picha takatifu. Kabla ya hapo alitetea imani sahihi kuhusu utashi wa kibinadamu wa Yesu Kristo. Maandishi yake machache yametufikia; kati yake ni maarufu zaidi yale kuhusu Bikira Maria. Anaheshimiwa tangu kale na Wakatoliki na Waorthodoksi kama mtakatifu. Sikukuu yake huadhimishwa tarehe 12 Mei.
