Irenei wa Srijem (alifariki Sirmium, leo Srijem nchini Korasya, 6 Aprili 304) alikuwa askofu kijana aliyekatwa kichwa kwa sababu ya imani yake katika dhuluma ya kaisari Maximian. Hakujali mateso yaliyotangulia wala mabembelezo ya wazazi, mke na watoto wake. Ndiyo maana anaheshimiwa tangu zamani na Wakatoliki, Waorthodoksi na Waorthodoksi wa Mashariki kama mtakatifu mfiadini. Sikukuu yake inaadhimishwa tarehe 6 Aprili.
