In Greek mythology, Agamemnon (; Ancient Greek: ; modern Greek:, " very steadfast ") was the son of King Atreus and Queen Aerope of Mycenae, the brother of Menelaus, the husband of Clytemnestra, and the father of Electra and Orestes.

On Agamemnon's return from Troy he was murdered ( according to the fullest version of the oldest surviving account, Odyssey 11. 409 – 11 ) by Aegisthus, the lover of his wife Clytemnestra.

When Agamemnon came home he was slain by either Aegisthus ( in the oldest versions of the story ) or Clytemnestra.

While Agamemnon, the son of Atreus, was absent on his expedition against Troy, Aegisthus seduced Clytemnestra, the wife of Agamemnon, and was so wicked as to offer up thanks to the gods for the success with which his criminal exertions were crowned.

In Greek mythology, Orestes (; ) was the son of Clytemnestra and Agamemnon.

Orestes was absent from Mycenae when his father, Agamemnon, returned from the Trojan War with the Trojan princess Cassandra as his concubine, and thus not present for Agamemnon's murder by his wife, Clytemnestra, in retribution for his sacrifice of their daughter Iphigenia to obtain favorable winds during the Greek voyage to Troy.

According to Pindar, the young Orestes was saved by his nurse Arsinoe ( Laodamia ) or his sister Electra, who conveyed him out of the country when Clytemnestra wished to kill him.

The story of Orestes was the subject of the Oresteia of Aeschylus ( Agamemnon, Choephori, Eumenides ), of the Electra of Sophocles, and of the Electra, Iphigeneia in Tauris, Iphigenia at Aulis ( in which he appears as an infant carried by Clytemnestra ), and Orestes, of Euripides.
