不合作运动（Non-cooperation movement），又称非暴力不合作运动，是世界历史上第一个全国性的非暴力反抗运动，由律师出身的印度国民大会党领袖圣雄甘地。他发动和领导了1920—1922年和1930—1934年全国范围的轰轰烈烈的非暴力不合作运动

一战结束后(1918年)，英国对印度的统治转趋严厉，反英运动随之兴起，要求独立自治的呼声高张。甘地呼吁以非暴力的不合作手段，抵制英国的统治。他要求印度人不纳税、不入公立学校、不到法庭、不入公职、不购买英货，并多次绝食。

为了展示抵制英货的决心，他甚至曾号召群众焚烧英国工厂所倾销于印度人民的衣物及公开制盐。甘地和平消极抵抗的方法，近乎瘫痪当地的殖民政府，并让其饱受各界尤其是英国国内的压力；迫使英国政府不得不颁布新宪法，让印度逐渐发展自治体制。
