Adriano wa Nikomedia (aliuawa tarehe 4 Machi 306) alikuwa mkuu wa walinzi wa kaisari Galerius. Alipokuwa na umri wa miaka 28, aliongokea Ukristo pamoja na mke wake Natalia, ilimbidi Adriano afie dini hiyo katika mji Nikomedia, leo nchini Uturuki. Tangu kale anaheshimiwa kama mtakatifu mfiadini. Sikukuu yake huadhimishwa na Waorthodoksi katika tarehe tofauti; kwa Wakatoliki ni tarehe 8 Septemba.
