塞克斯图斯·恩丕里柯（希腊语：Σέξτος Ἐμπειρικός，英语：Sextus Empiricus；160年－210年）是希腊医生与哲学家。怀疑论者，主张：若任何人宣称有标准能判断真理，如果那标准未经检验，如何能以之判断；又如果那标准已经过验证，又是以何为准验证的？因此，塞克斯图斯认为无法找到足够的标准来验证真理。

Sextus Empiricus (Greek: Σέξτος Ἐμπειρικός; c. 160 – 210 CE), was a physician and philosopher, and has been variously reported to have lived in Alexandria, Rome, or Athens. His philosophical work is the most complete surviving account of ancient Greek and Roman skepticism.
