Heracles
Heracles's name transparently combines 'Hera' with kleos ('glory, fame'), literally meaning 'Glory of Hera' - a name ancient sources themselves recognized as sharply ironic, since Hera was his lifelong persecutor rather than his patron.

Meaning
Heracles is one of the clearest and most secure name etymologies in the whole Greek mythological corpus. It is a transparent compound of Hēra, the name of Zeus's wife, and kleos, the common Greek noun for 'glory,' 'fame,' or 'renown,' the same word that anchors epic poetry's central value system, since kleos is what a Homeric hero is fighting to win. Put together, Hēraklēs means, straightforwardly, 'Glory of Hera' or 'he who has glory through Hera.' Unlike Hephaestus, Persephone, or Dionysus, there is no live scholarly dispute over what the individual pieces of this name mean; the only real question the name raises is not linguistic but interpretive: why would this hero, of all figures, carry the name of the goddess who tormented him? Ancient sources address this directly rather than leaving it as an unexplained irony. According to the tradition preserved by Diodorus Siculus, the hero was originally named Alcides, after his grandfather Alcaeus, and only renamed Heracles later, following a well-known episode in which the infant strangled two serpents Hera had sent into his cradle. The renaming, in this account, deliberately honors the very persecution that shaped his life: he 'won glory through Hera,' as the ancient explanation puts it, precisely because her hostility set in motion the trials, most famously the Twelve Labors, through which he became mythology's greatest hero. Some later interpreters have also suggested the name functioned as a kind of protective appeasement, a common naming pattern in which a feared or hostile power is honored directly in hopes of softening it. The name's Latin form, Hercules, is a straightforward Roman adaptation of the Greek Hēraklēs rather than an independent formation with its own etymology; Latin simply absorbed the Greek compound and adjusted its ending to fit Latin phonology, carrying the 'Glory of Hera' meaning across languages largely unchanged.
What does the name Heracles literally mean?
It is a straightforward compound of Hera, Zeus's wife, and kleos, the Greek word for 'glory' or 'fame,' together meaning 'Glory of Hera.' Unlike many mythological names, this etymology is not seriously disputed; the compound is transparent and grammatically regular, one of the clearest name derivations in Greek myth.
Why is Heracles named after Hera when she was his enemy?
Ancient sources treat this as a deliberate irony rather than an accident. According to Diodorus Siculus, the hero was originally called Alcides and was renamed Heracles after surviving Hera's attempt on his life as an infant, on the reasoning that he ultimately 'won glory through Hera,' since her hostility set in motion the trials that made him famous.

What was Heracles called before he was named Heracles?
According to the tradition Diodorus Siculus records, he was first named Alcides, after his grandfather Alcaeus, and only received the name Heracles later, following the episode in which he strangled two serpents Hera sent to kill him in his cradle.
Is 'Hercules' a different name from 'Heracles'?
No, Hercules is simply the Latin adaptation of the Greek Hēraklēs, carrying the same 'Glory of Hera' meaning across languages. Latin did not independently coin the name or give it a separate etymology; it borrowed the Greek compound and reshaped only its ending to fit Latin grammar.
Do scholars dispute the Hera-plus-kleos etymology of Heracles?
No, not in any serious way. Compared with genuinely contested names like Hephaestus or Persephone, Heracles's etymology is considered one of the most secure in Greek myth: both elements are ordinary, well-understood Greek words, and the compound follows regular Greek name-formation patterns exactly.
