盗尸是指盗取尸体的行为。

中国的盗墓或发冢通常不盗尸体，而是陪葬品，尸体是无法交换金钱的物质。但也有一些性变态者喜欢盗女尸予以奸淫，更有一些农村盛行阴婚（鬼婚），没有成婚的男性在去世后，由家人为其寻找一位女性尸体合葬，因此常有女尸被盗。盗尸有时是为了鞭尸泄恨，《清史稿·姚立德传》卷325记载，吏部侍郎姚立德为官严谨，“阳谷民王伦为乱，立德分守东昌，城圮难守，引运河水绕城壕，恃以为固；檄发伦先墓，磔其尸。”饥荒时期也有人盗尸食尸。明朝正统年间，在山东济南一带有辱尸“抗旱”的迷信，大旱之年，开棺辱尸，磔其手足，称之“打旱骨桩”。张冀曾向明英宗朱祁镇上书，希望严禁。纪晓岚在《阅微草堂笔记》写道，“掘而焚之，亦往往致雨”。

Body snatching is the secret disinterment of corpses from graveyards or other burial sites. A common purpose of body snatching, especially in the 19th century, was to sell the corpses for dissection or anatomy lectures in medical schools. Those who practiced body snatching were often called "resurrectionists" or "resurrection-men". A related act is grave robbery, uncovering a tomb or crypt to steal artifacts or personal effects rather than corpses.
