Dimitri wa Thesalonike (kwa Kigiriki Άγιος Δημήτριος της Θεσσαλονίκης; alifariki 306 hivi) alikuwa Mkristo wa Sirmium (leo nchini Serbia) ambaye alifia dini yake katika dhuluma ya Kaisari Dioklesyano. Kwa sababu hiyo tangu kale anaheshimiwa na Wakatoliki, Waorthodoksi na Waorthodoksi wa Mashariki kama mtakatifu. Sikukuu yake huadhimishwa katika tarehe mbalimbali; kwa Wakatoliki ni tarehe 9 Aprili.
