Juventino na Masimino (walifariki Antiokia, leo nchini Uturuki, 29 Januari 363) walikuwa askari walinzi wa kaisari Juliani Mwasi waliouawa kwa ajili ya imani yao ya Kikristo. Tangu kale wanaheshimiwa kama watakatifu wafiadini. Sikukuu yao huadhimishwa tarehe 29 Januari. Watakatifu wa Agano la Kale Orodha ya Watakatifu Wakristo Orodha ya Watakatifu wa Afrika Orodha ya Watakatifu Wafransisko Saint John Chrysostom wrote a panegyric concerning them. Cfr. Butler, Alban. "St. Juventinus and St. Maximinus, Martyrs", The Lives of the Saints. 1866 Chrysostom makes the point that they were executed in the middle of the night on a charge of high treason, as Julian did not want to make martyrs of them by suggesting they died because of their faith.
