The name Ctesippus may also refer to a character in Plato's Euthydemus and Lysis, and to a historical figure, see Leptines and Against Leptines.

In Greek mythology, the name Ctesippus (/tɪˈsɪp.əs/;^[1] Ancient Greek: Κτήσιππος means 'possessing horses') may refer to:

• Ctessipus, son of Heracles by Deianira.^[2] He was the father of Thrasyanor, grandfather of Antimachus and great-grandfather of Deiphontes.^[3] Thersander, son of Agamedidas, is also given as his great-grandson.^[4]
• Ctesippus, another son of Heracles by Astydameia the daughter of Amyntor or Ormenius.^[5]
• Ctessipus, two of the suitors of Penelope, one from Same, and the other from Ithaca.^[6] The rich and "lawless" Ctesippus of Same, son of Polytherses, who has 'fabulous wealth' appears in the Odyssey; he mocks the disguised Odysseus and hurls a bull's hoof at him as a 'gift', mocking xenia, though Odysseus dodges this. Telemachus says if he had hit the guest, he would have run Ctesippus through with his spear.^[7] Later, in the battle between Odysseus and the suitors, Ctesippus attempts to kill Eumaeus with a spear, but misses due to Athena's intervention, though scratches Eumaeus's shoulder, and is thereupon himself killed by Philoetius, who thus avenges the disrespect towards his master.^[8]
