Pan You (潘佑 ; 938–973) was a politician of the Southern Tang who was arrested by Li Yu and killed by hanging. Pan You was born in Youzhou, now modern Beijing.

During the Southern Tang there were many officials that tried to use the Rites of Zhou to reform the law but failed. Pan You was familiar with classics and history, including the works of Laozi and Zhuangzi. He enjoyed writing and once wrote a thousand word letter to the Southern Han. He authored the 10-volume work "Xingyang Collection" (滎陽集), which is now lost.

Li Yu, ruler of the Southern Tang, lived a luxurious life. During his reign, Pan You went to court seven times and was severely criticized for his writing on politics. During the decline of the Southern Tang, Pan's writings provoked the anger of Li Yu. As a result, Li Yu sent people to arrest and kill Pan You, poisoned Lin Renzhao, and Pan You died by hanging.

In 978, Li Yu confessed to killing Pan You.

Pan You's life was documented in Book of Southern Tang by Ma Ling, the 1184 Book of Southern Tang by Lu You, the 1343 History of Song and Volume 4 of the Junzhai Chronicle (郡斋读书志).

Pan was ugly and got divorced.

潘佑（938年 - 973年），幽州（今北京）人。南唐政治人物。

南唐時，累官虞部員外郎、內史舍人。借《周禮》變法，失敗。佑博通經史，尤喜老莊之言，文思敏捷，詞採斐然。其所草勸南漢書，累數千言，情辭款洽，甚有時譽。復擅行書草帖。著有《滎陽集》十卷，已佚。

後主李煜生活奢侈，潘佑七次上疏，徐鉉、張洎排斥潘佑，開寶六年，後主繫之獄，潘佑自殺。

978年，徐鉉奉宋太宗之命探視李煜，李煜嘆息：「當初我錯殺潘佑、李平，悔之不已！」

生平散見馬令《南唐書》、陸游《南唐書》、《宋史》本傳、《郡齋讀書志》卷四中。

潘佑貌醜，娶嚴續女，嚴氏很美貌。後來有一次嚴氏早上化妝，潘佑偷看，嚴氏從鏡子中看到他，嚇得倒地。潘佑覺得她厭惡自己，就和她離婚了。
