Antiphon of Rhamnus (/ˈæntɪfɒn, -ən/; Ancient Greek: Ἀντιφῶν ὁ Ῥαμνούσιος; 480–411 BC) was the earliest of the ten Attic orators, and an important figure in fifth-century Athenian political and intellectual life.
There is longstanding uncertainty and scholarly controversy over whether the Sophistic works of Antiphon and a treatise on the Interpretation of Dreams were also written by Antiphon the Orator, or whether they were written by a separate man known as Antiphon the Sophist. This article only discusses Antiphon the Orator's biography and oratorical works.
