韩非（约前281年－前233年），生活于战国末期时期的韩国（今属河南省新郑市）的思想家，为中国古代著名法家思想的代表人物，认为应该要「法」、「术」、「势」三者并重，是法家的集大成者。

韩非出身韩国宗室贵族，与李斯学于荀子，后因其学识渊博，被秦始皇召唤入秦，正欲重用，却遭到妒忌的同窗李斯害死，在韩非死后，秦始皇在他的思想指引下，完成统一六国的帝业。

韩非其学出于荀子，源于儒家，而成为法家，又推究老子思想，归本于道家。司马迁指出韩非喜好「刑名法术」且归本于道家的「黄老之学」，一套由「道」、「法」共同完善的政治统治理论。

Han Fei (traditional Chinese:韓非; simplified Chinese:韩非; [xǎn féi̯]; c.280 –233 BC), also known as Han Feizi, was an influential political philosopher of the Warring States period "Chinese Legalist" school. Han synthesized the methods of his predecessors, as described in his eponymous work, the Han Feizi. His writings were very influential on the future first emperor of China, Qin Shi Huang. After the early demise of the Qin Dynasty Han's philosophy was officially vilified by the following Han Dynasty. Despite its outcast status throughout the history of imperial China, his political theory continued to heavily influence every dynasty thereafter, and the Confucian ideal of a rule without laws was never again realized.
