Anaxagoras (; , Anaxagoras, "lord of the assembly"; c. 510 – 428 BC) was a Pre-Socratic Greek philosopher. Born in Clazomenae in Asia Minor, Anaxagoras was the first to bring philosophy to Athens. According to Diogenes Laertius and Plutarch, in later life he was charged with impiety and went into exile in Lampsacus; the charges may have been political, owing to his association with Pericles.

Anaxágoras (en griego Αναξαγόρας) (500 - 428 a. C.) fue un filósofo presocrático que introdujo la noción de nous (νοῦς, mente o pensamiento) como elemento fundamental de su concepción física.
