Donato Mkuu kutoka Casae Negrae alikuwa askofu wa Karthago (leo nchini Tunisia) kuanzia mwaka 313. Alishika msimamo mkali dhidi ya Wakristo walioasi ili kuokoa uhai wao wakati wa dhuluma ya kikatili ya Dola la Roma dhidi yao, hasa chini ya Kaisari Dioklesian. Kwa ajili hiyo alisababisha farakano kubwa ambalo lilipewa jina lake na kuenea hasa kati ya Waberberi, kabila lake. Alifariki mwaka 355 uhamishoni. Beaver, R. Pierce, “The Donatist Circumcellions”.
