持不同意見是一種情緒或哲學，不同意或反對一個流行的想法(如政府的政策)或一個實體(如支持這些政策的個人或政黨)。這個術語的反義詞包括協議、共識(當所有或幾乎所有各方都同意某事時)和同意(當一方同意另一方提出的建議時)。在一些政治制度中，異議可以通過反對派政治的形式正式表達，而政治壓迫性政權可能禁止任何形式的異議，從而導致壓制異議和鼓勵社會或政治行動主義。不遵守或不支持某些國家政策的個人被稱為“持不同政見者”。一些思想家認為，一個健康的社會不僅需要保護，而且需要鼓勵持不同意見的人在1843年寫給阿諾Ruge,馬克思寫道:“如果未來建設和解決一切都不是我們的事情,更加清楚的是我們目前必須完成:我指的是無情的批評的存在,無情的感覺不害怕結果到達和的感覺就像小害怕沖突的權力是
