(Ἐχέδημος), the chief of the Athenian embassy which was sent, in B. C. 190, to meet Publius and Lucius Scipio at Amphissa, and to obtain peace for the Aetolians. When the consul Lucius refused to recede from the hard terms which had been already proposed by the senate, the Aetolians, by the advice of Echedemus, applied for and obtained a truce of six months, that they might again send ambassadors on the subject to Rome. (Plb. 21.2, 3; Liv. 37.6, 7.)
