神医，又称巫医，是透过神明、邪灵、符咒、巫蛊等超自然力量来行医治病的人。

巫医起源甚早，《大荒西经》云：“有灵山，巫咸、巫即、巫彭、巫姑……十巫从此升降，百药爰在。”《离骚》中有二次提到“彭咸”。王逸《楚辞章句》注称“彭咸，殷贤大夫，谏其君，不听，自投水而死。”《说文》称“古者巫咸初作巫”。巫医的医疗过程中掺杂许多符咒与迷信。

周朝后期，巫与医开始分歧，《论语·子路》曾记载“人而无恒，不可以作巫医”，《十三经注疏》说：“巫主接神去邪，医注疗病”。《论衡·言毒》载：“巫咸能以祝延人之疾”。到了唐朝仍有巫医的行业，韩愈《师说》：“巫医乐师百工之人，君子不齿。”。今日医学昌明的时代，巫医往往被视为神秘和迷信。

A witch doctor was originally a type of healer who treated ailments believed to be caused by witchcraft. The term witch doctor is sometimes used to refer to healers, particularly in third world regions, who use traditional healing rather than contemporary medicine. In contemporary society, "witch doctor" is sometimes used derisively to refer to chiropractors, homeopaths and faith healers.
