In a communication commending Euphraeus to Perdiccas III, Euphraeus is criticized for his lack of aptitude for political philosophy.
Euphraeus (Ancient Greek: ; fl. c. 4th century BC; d. ca. 342 BC/341 BC) was a philosopher and student of Plato from the town of Oreus in northern Euboea. Little is said about Euphraeus in the Fifth Letter of Plato beyond his aptitude for political philosophy, and the letter's authenticity has been challenged. The letter commends Euphraeus to Perdiccas III, king of Macedon.
