Atreus Origin and Meaning
The name Atreus is a boy's name of Greek origin meaning "fearless".
This unusual name from Greek mythology is gaining traction along with others in its class, such as Atlas, Artemis, and Apollo. The King of Mycenae (to where he'd been banished, after murdering his half-brother) , Atreus was also the father of King Agamemnon, an important commander in the Trojan War.
The name entered the US Top 1000 in 2019 and in a recent year, it appeared in the Top 500. It has a number of different pronunciations, including the Classic Greek AY-TREWS and the contemporary sounding uh-tray-us, inspired by the character in video game Franchise, God of War.
The popularity of Atreus has led to some parents considering Atreides, a spin on the Greek name that appears in the Dune novels and subsequent films.
