In Greek mythology, Astylochus (Ancient Greek: Ἀστύλοχος) was one of the suitors of Penelope who came from Dulichium along with either 56 other wooers (according to Apollodorus), or 51 (according to Homer). He, with the other suitors, was slain by Odysseus with the aid of Eumaeus, Philoetius, and Telemachus.
