Dercylidas (Δερκυλἰδας) was a Spartan commander during the 4th century BC. For his cunning and inventiveness, he was nicknamed Sisyphus. In 411 he was harmost at Abydos. From 399 to 397 BC, Dercylidas superseded Thibron and led the Spartans through Thrace to the west coast of Asia, where he plundered Bithynia and Eolia. After allying himself with Tissaphernes and Meidias, Dercylidas attacked Pharnabazus. In 394, King Agesilaus sent Dercylidas from Amphipolis to the Hellespont. In 396 Dercylidas was himself succeeded by King Agesilaus.
