Peisander or Pisander (Ancient Greek: Πείσανδρος) son of Antimachus is a Trojan warrior, brother of Hippolochus. In Iliad 11 the pair beg Agamemnon for mercy and ransom, naming their rich father; Agamemnon refuses and slays them because Antimachus had urged the Trojans to kill Menelaus when he came as envoy. He is distinct from Bellerophon's Lycian son, from Menelaus' other Trojan victim of the same name, and from Penelope's suitor from Same.

I.Son of Antimachus
Homer makes Peisander and Hippolochus sons of Antimachus, the Trojan who took Paris' gold and spoke against returning Helen. When Agamemnon catches the brothers, they clasp his knees and offer ransom; he remembers their father's counsel and kills both.
Quintus Smyrnaeus also places Peisander among Antimachus' sons. Handbooks keep him separate from the Peisander Menelaus kills elsewhere in the Iliad and from the Myrmidon company-leader son of Maemalus.
