Percy Jackson Baby Names: Demigod Picks That Wear Like Everyday Names

Here is the trick Rick Riordan pulled off in Percy Jackson & the Olympians: the children of the Greek gods are not draped in marble and thunder. They are American kids with backpacks and ADHD and very normal names. Percy is just a boy named Percy until the minotaur shows up. Annabeth could be in any seventh-grade homeroom in the country. The myth hums underneath the ordinary, and that is exactly what makes these names so usable for a real baby. It is also the reason the books reread so well — the magic is never in the costume, it is in the gap between the ordinary name on the roll sheet and the ancient bloodline behind it.

So this is not a Greek mythology lecture dressed up as a baby-name list. It is a demigod field guide. Most of Riordan’s heroes wear names a modern parent could put on a birth certificate without a second thought, while the gods themselves are a braver, louder proposition. And a handful of names in this universe are welded so tightly to a monster or a single character that they belong on the page, not the nursery door.

Below, an honest three-way sort — the wearable demigods and mortals first, then the Olympian names you’d need some nerve to use, then the ones to admire from a safe distance. Real etymologies throughout, and a closing read on how loudly each choice announces the fandom.

The demigods and mortals: fully wearable, real names today

This is the heart of it. Riordan stocked Camp Half-Blood and the Roman camp with names that were already in circulation, which means a child wearing one of these reads first as a person and only second as a reference.

• Percy (English, short for Perseus) — The narrator and son of Poseidon. Percy is an old English surname-name (think Percy Bysshe Shelley) and a short form of Perseus, the hero who slew Medusa. Gentle, a little vintage, and rising for boys. Worth knowing: the name carries no sea connotation at all on its own — the Poseidon link is pure Riordan, which is exactly why it feels like a wink rather than a label.
• Annabeth (Hebrew + English compound) — Daughter of Athena and the series’ sharpest mind. Genuinely a real name: Anna (Hebrew, “grace”) welded to Beth (short for Elizabeth). Wears beautifully on its own, and splits into two ready-made nicknames — Anna or Beth — if a child ever wants to step back from the full mythic version.
• Luke (Greek/Latin, “from Lucania” or “light”) — The tragic son of Hermes. Luke predates and outshines the series entirely — a longtime favorite that signals almost nothing of the fandom. Its New Testament pedigree as the evangelist Luke gives it a depth no villain arc can dent.
• Hazel (English, the tree and its warm brown color) — Hazel Levesque, daughter of Pluto, a standout of Heroes of Olympus. A vintage botanical name fully back in fashion on its own merits. Ranks No. 19.
• Piper (English occupational, “one who plays the pipe”) — Daughter of Aphrodite with a charmspeaker’s voice. Already a popular modern name with zero need of the books to justify it. Ranks No. 160.
• Jason (Greek, “healer”) — The Roman counterpart hero, named for the original Argonaut. A classic that long predates Camp Jupiter. There is a quiet irony Riordan surely enjoyed: the myth’s Jason was a famously flawed leader, while the books’ Jason is the dutiful golden boy. Ranks No. 148.
• Leo (Latin, “lion”) — The fire-wielding son of Hephaestus and the series’ comic heart. Leo is a hugely popular name today and reads as the zodiac lion long before it reads as Valdez. Ranks No. 24.
• Frank (Germanic, “free man” / a Frank) — Frank Zhang, son of Mars, steady and brave. Frank is an old-fashioned-handsome name that quietly fits the brave theme. Ranks No. 468.
• Nico (Italian, short for Niccolò/Nicholas, “victory of the people”) — Nico di Angelo, son of Hades. A genuine Italian short form with real history and a soft, current sound. Ranks No. 213.
• Reyna (Spanish, “queen”) — The Roman praetor and one of the saga’s strongest leaders. Reyna is a real Spanish name meaning exactly what her character embodies.
• Will (English, short for William, “resolute protector”) — Will Solace, healer and son of Apollo. About as safe and warm as a boy’s name gets; the reference is invisible. Ranks No. 10.
• Sally (Hebrew, short for Sarah, “princess”) — Percy’s loving, fiercely human mother. A retro-sweet nickname-name having a quiet revival, and a rare case where the most ordinary name in the book belongs to its most quietly heroic character.
• Rachel (Hebrew, “ewe”) — Rachel Elizabeth Dare, the mortal Oracle. A timeless Hebrew classic that carries no fandom weight at all. Ranks No. 247.
• Meg (English, short for Margaret, Greek “pearl”) — Meg McCaffrey, the prickly young demigod who commands the disgraced god in The Trials of Apollo. Fully wearable in either form: Meg is bright and unfussy, while Margaret is bedrock-classic with centuries of saints and queens behind it. Ranks No. 119.
• Lavinia (Latin, from Lavinium; the legendary mother of the Roman people) — A New Roman camper in Trials of Apollo. The name long predates Riordan in Virgil’s Aeneid, and its frilly, old-Italian charm makes it a genuine soft-spoken option for a daring parent.
• Grover (English, “dweller by a grove”) — The loyal satyr who finds Percy. Technically a satyr, but the name itself is a real, gently revived presidential surname-name — usable if you love it.
• Clarisse (French/Latin, “bright, clear”) — The gruff daughter of Ares. A genuine variant of Clarice, vintage and a touch fierce. The shared clar- root with Clara and Clarity gives a tough character a surprisingly luminous name.
• Silena (likely from Selene/Greek roots, “moon”-adjacent) — A daughter of Aphrodite. Uncommon and pretty, with a soft moonlit sound, though it leans rare.
• Charles “Charlie” (Germanic, “free man”) — Charles Beckendorf, the brave son of Hephaestus. Charles is bedrock-classic; only the surname Beckendorf nods to the books, and it is German in origin — a place-name ending in -dorf, “village” — so it stays firmly a surname, not a first name. Ranks No. 51.
• Castor and Pollux (Greek/Latin; the Dioscuri twins) — The twin sons of Dionysus at Camp Half-Blood, named for the mythic horseman-and-boxer pair who became the constellation Gemini. Castor (“beaver”) is the more usable of the two, with a soft sound and a real if rare history; Pollux is bolder and stays close to the page.

Borrowed straight from Olympus: god and Titan names for the brave

These are the names Riordan took directly from the divine roster. Some have quietly crossed into real-world use; others are a bold, capital-letter statement. Worn on a child, they announce the source far more loudly than a Percy or a Hazel ever would.

• Apollo (Greek, god of the sun, music, and prophecy) — The radiant Olympian who gets his own spin-off series, where he is exiled to Earth as the gawky teenager Lester Papadopoulos. A striking, increasingly used boys’ name with obvious solar energy. Ranks No. 414.
• Athena (Greek, goddess of wisdom and strategy) — Annabeth’s mother and patron of clever heroes. A genuinely wearable goddess name that has entered real use. Ranks No. 90.
• Artemis (Greek, goddess of the hunt and the moon) — Leader of the Hunters. Bold worn in full; many parents reach for the gentler nickname Artie or pair it with the moon imagery it carries. Worth noting the name is pre-Greek in origin, so old that even the ancients had stopped agreeing on what it meant.
• Selene (Greek, “moon”; the Titan goddess of the moon herself) — The older lunar deity behind Artemis’ moon imagery, glimpsed across the wider mythos. Among the god names this is the most quietly wearable: soft, luminous, and already used by real families who love the moonlit sound without ever opening the books. Ranks No. 675.
• Hermes (Greek, messenger god) — Luke’s father and patron of travelers and tricksters. Distinctive and rarely used as a given name, but undeniably handsome. The modern luggage house borrowed the name from the same god, which can cut either way depending on the ear.
• Hestia (Greek, goddess of the hearth and home) — The gentlest Olympian, keeper of the fire. Warm, soft, and uncommon — an under-the-radar pick with a lovely meaning, and one of the very few divine names whose associations are entirely peaceful.
• Iris (Greek, goddess of the rainbow; also the flower) — The messenger goddess behind Iris-messaging. Fully mainstream as a botanical name, with a mythic bonus. Ranks No. 71.
• Persephone (Greek, queen of the underworld and goddess of spring) — The stepmother figure of the Hades household and the maiden of the Demeter myth. A dramatic, four-syllable choice, but a real if bold girl’s name with a built-in nickname in Percy or Seph, and a meaning that swings beautifully between flowers and shadow.
• Demeter (Greek, goddess of the harvest and grain) — Persephone’s grieving mother and the deity who gives the world its seasons. Heavier and more obscure as a given name than her daughter’s, but warm-sounding and genuinely meaningful for a family drawn to growth and earth imagery.
• Hecate (Greek, goddess of magic, crossroads, and the night) — The divine parent of Lou Ellen’s cabin. A boldly witchy choice, pronounced HEK-uh-tee, and far closer to the page than the nursery — but for a family who wants the magic loud and unmistakable, it is a real theonym with deep roots.
• Calypso (Greek, “she who conceals”) — The Titaness who befriends Percy and later Leo. Lush and musical, rare but genuinely usable for a daring parent.
• Bianca (Italian, “white”) — Bianca di Angelo, a Hunter of Artemis and Nico’s sister. A fully real Italian name that stands entirely on its own.
• Zoe (Greek, “life”) — Zoë Nightshade, the noble lieutenant of the Hunters. The character is mythic, but Zoe is a hugely popular real name meaning “life.” Ranks No. 29.
• Thalia (Greek, “to blossom”; one of the Muses and Graces) — The fierce daughter of Zeus. A real, blooming Greek name with bright mythological roots well beyond the series. Ranks No. 658.
• Diana (Latin, the Roman Artemis) — The huntress in her Roman form. A timeless Latin classic with no fandom baggage. Ranks No. 243.

Roman and minor-myth names worth a look

The Heroes of Olympus arc folds in the Roman pantheon and a wider cast, which adds a few more names that ride the line between mythic and modern.

• Hylla (from Greek myth, sister of Reyna; echoes Hyllus) — The Amazon queen. Quite rare and tied to the character, but short and strong if you want something truly unusual.
• Octavian (Latin, “eighth”; the historical Augustus’ name) — The scheming augur of Camp Jupiter. The character is a villain, but the name is a genuine, grand Roman classic, and the gentler Octavia has had real currency for girls.
• Gwen / Gwendolyn (Welsh, “white, blessed”) — A Roman legionnaire. A real, lovely Welsh name with no mythic weight to carry.
• Dakota (Native American / Sioux, “friend, ally”) — A Roman camper. A familiar modern unisex name independent of the books.
• Lou Ellen (English compound) — A daughter of Hecate. The pieces (Lou + Ellen) are real and retro-charming, though the pairing is the author’s.

Admire on the page: character and monster names to skip

Honesty matters here. Some names in this world are pure character — or pure monster — and putting them on a child would be a heavy lift no etymology can rescue.

• Tyson — A wonderful, gentle Cyclops and Percy’s half-brother. Tyson is a real surname-name, but it reads as the boxer or the Cyclops, not as a classic given name.
• Lester — Apollo’s mortal alias in The Trials of Apollo, and the joke is that it is deliberately unglamorous: a dusty old occupational surname meaning roughly “from Leicester.” That is the point of the character, and it is also why it stays firmly on the page.
• Chiron — The wise centaur trainer. Beautiful meaning, but the sound and the centaur association make it character-only for most families.
• Polyphemus, Medusa, Kronos, Gaea, Tartarus — Titans, monsters, and primordial threats. These are the antagonists of the saga; admire them in the story and leave them there.
• Ares — The god of war is a real Greek theonym, but as a baby name it is heavy, harsh, and tightly bound to a brutal deity. Better to borrow the bravery and not the name.

How loudly does it announce the fandom?

Every name on this list signals the source at a different volume. Here is how to choose based on how much of Camp Half-Blood you want a stranger to hear.

Whisper-quiet: nobody will know unless you tell them

Jason, Leo, Luke, Hazel, Piper, Iris, Zoe, Diana, Rachel, Will, Charles, Meg, and Bianca all predate or out-circulate the series. These are real, popular names first; the demigod connection is a private wink you carry, not a flag anyone else sees.

A knowing nod: fans will catch it, strangers won’t

Percy, Annabeth, Nico, Reyna, Frank, Thalia, Lavinia, Selene, and Clarisse sit in the sweet spot. They are completely real and usable, but a fellow reader will light up when they hear them. This is where most Percy Jackson families land — a name that fits a whole life and still earns a grin at the bookstore.

Full quest banner: this name shouts Olympus

Apollo, Athena, Artemis, Calypso, Hermes, Hestia, Persephone, and Hecate wave the flag high. They are gorgeous and increasingly brave parents are using them, but there is no hiding a small Apollo or Athena’s mythic origins. Choose these if you want the myth out loud, not underneath.

That layering — the everyday name with the ancient story humming beneath it — is the real gift Riordan gives expecting parents. You do not have to choose between a name your child can actually live in and a name with depth and meaning. A Percy, an Annabeth, a Hazel, or a Nico gets to be a regular kid at roll call and, quietly, the heir to something old and brave. The trilogy-spanning point is the same one the books make about the demigods themselves: the power was never in sounding mythic, it was in carrying the old story lightly while living an ordinary, wide-open life. That is the best kind of name — one that fits the playground and the prophecy both.
