In Greek mythology, Acessamenus (Ancient Greek: Ἀκεσσαμενοῖο) was a king of Pieria. He was known as the founder and eponym of Akesamenai, a city in Macedonia.

In the Iliad, Acessamenus is mentioned as father of several daughters, the eldest of whom, Periboea, had a son Pelagon by the river god Axius; Pelagon, in his turn, was the father of the Trojan ally Asteropaios.

"Meanwhile the son of Peleus (i.e. Achilles) bearing his far-shadowing spear leapt, eager to slay him, upon Asteropaeus, son of Pelegon, that was begotten of wide-flowing Axius and Periboea, eldest of the daughters of Acessamenus; for with her lay the deep-eddying River."
