《女人皆如此，或恋爱学堂》（Così fan tutte, ossia La scuola degli amanti，作品号K.588）为莫札特所作喜歌剧，剧本由洛伦佐·达·彭特（Lorenzo da Ponte）撰写。莫札特有三部歌剧作品的剧本都由彭特所作（女人皆如此、唐·乔望尼与费加洛婚礼）。这出剧是在神圣罗马帝国皇帝约瑟夫二世（Emperor Joseph II）的建议下进行创作，原本规划是由作曲家萨列里（Antonio Salieri）为这剧本谱曲，但不知何故，在他完成第一幕的部分后即中断创作。这个标题「Così fan tutte」原意为「女人们都这么做的」，不过通常翻译为「女人皆如此」，这段文本在剧中第二幕终曲前由三名男士所唱出。
