法勒鲁姆的德米特里，或称法勒鲁姆人德米特里（希腊语：Δημήτριος Φαληρεύς , 约前350年－约前280年），是雅典的演辩家、政治家、哲学家、作家。他出身法勒鲁姆（Phalerum），后来成为泰奥弗拉斯托斯的学生，也是早期逍遥学派的其中一员。德米特里之后成为杰出的政治人物，并被马其顿的卡山德命为雅典的僭主。德米特里单独治理雅典10年，期间对法律进行重要改革，并让雅典维持亲卡山德的寡头政治。一直到前307年，德米特里遭到卡山德敌对势力驱除出境，于是他被迫离开雅典，来到底比斯，并在前297年后来到亚历山卓托勒密宫廷。他留下许多著作，包含历史、修辞学和文学批评等项目。

Demetrius of Phalerum (also Demetrius of Phaleron or Demetrius Phalereus; Greek: Δημήτριος Φαληρεύς; c. 350 – c. 280 BC) was an Athenian orator originally from Phalerum, a student of Theophrastus, and perhaps of Aristotle, himself, and one of the first Peripatetics. Demetrius was a distinguished statesman who was appointed by the Macedonian king, Cassander, to govern Athens, where he ruled as sole ruler for ten years, introducing important reforms of the legal system while maintaining pro-Cassander oligarchic rule. He was exiled by his enemies in 307 BC, and he went first to Thebes, and then, after 297 BC, to the court of Alexandria. He wrote extensively on the subjects of history, rhetoric, and literary criticism.
