多数人暴政（英语：Tyranny of the majority），又称为多数暴力，群体暴政，是指违反民主制度及“少数遵从多数”制度的行为而创造出来的一个政治词汇，用于批评由多数人作完全决定的的制度，将此原则与专制主义相提并论，认为在该制度中将多数人的利益绝对置于少数人之上，使得少数丧失了受尊重权。“多数人暴政”与“少数服从多数”制度是有区别的。“少数服从多数”制度制定的规则相同适用于多数人和少数持异见者，但部分“多数人暴政”则对不同的人制定不同的规则，让某些政治势力能在无法获得多数民意授权的状况下，依旧能实现其政治目的的手段。

The phrase "tyranny of the majority" (or "tyranny of the masses") is used in discussing systems of democracy and majority rule. It involves a scenario in which decisions made by a majority place its interests above those of an individual or minority group, constituting active oppression comparable to that of a tyrant or despot. In many cases a disliked ethnic, religious, political, or racial group is deliberately penalized by the majority element acting through the democratic process.
