Brasidas () (died 422 BC) was a Spartan officer during the first decade of the Peloponnesian War. He was the son of Tellis and Argileonis, and won his first laurels by the relief of Methone, which was besieged by the Athenians (431 BC). During the following year he seems to have been eponymous ephor (Xen. Hell. ii. 3, 10), and in 429 he was sent out as one of the three commissioners (o'bu/3ovXoi) to advise the admiral Cnemus. As trierarch he distinguished himself in the assault on the Athenian position at the Battle of Pylos, during which he was severely wounded (Thuc. iv. II. 12).
