全氟辛烷磺酸（英語：Perfluorooctanesulfonic acid，PFOS，共軛酸鹼對為全氟辛烷磺酸根），是一種人造的含氟表面活性劑和環境污染物。全氟辛烷磺酸是3M公司生產的思高潔（英語：Scotchgard）(Scotchgard)等多種去污劑中的關鍵成分。2009年5月，PFOS列入到斯德哥爾摩環境保護國際公約附件B中^[6]。PFOS可以在工業生產中合成，也可以由前體的降解產生。在野生動植物中檢測到的全氟辛烷磺酸水平被認為足以影響健康參數，最近發現全氟辛烷磺酸的血清水平升高與美國普通人群罹患慢性腎臟病的風險增加相關^[7]。「這種相關聯繫獨立於諸如年齡，性別，種族/民族，身高體重指數，糖尿病，高血壓和血清膽固醇水平等混雜因素。」 ^[7]。

它在2023年被列入IARC第2B類致癌物質。^[8]
