The Harry Potter franchise — books published 1997–2007, films 2001–2011 — had billions of fans and produced some of the most beloved fictional characters in modern culture. What did it do to baby names?
The answer, backed by SSA data, is more complicated than you'd expect: one HP name became a top-15 name; the most beloved female character is still nearly unused; and the franchise's most directly associated name (Harry) actually fell during the HP era.
Luna — from #1,318 to #13
The biggest HP naming story is Luna — Luna Lovegood, introduced in Harry Potter and the Order of the Phoenix (2003). Luna was at #1,318 in 2000 and is now #13 with 7,135 babies — the most dramatic rise of any HP-associated name.
| Year | Luna Rank |
|---|---|
| 2000 | #1,318 |
| 2005 | ~#685 |
| 2010 | ~#388 |
| 2015 | ~#113 |
| 2020 | #25 |
| 2024 | #13 |
The HP connection is real but may not be the whole story. Luna is also:
- Latin for moon (the celestial naming trend is real)
- Spanish for moon (significant in US Hispanic communities)
- A natural nature/celestial name with the same appeal as Nova, Aurora, and Stella
Luna's rise tracks the HP franchise but also tracks the broader celestial naming movement. Both effects are probably real. Luna Lovegood made the name possible; the celestial trend made it popular. See mythological names.
Lily — from #124 to #24
Lily — Lily Potter is Harry's mother, one of the most important characters in the HP mythology. Lily went from #124 in 2000 to #24 in 2024. But Lily was already rising before the HP films, and it's also the straightforward flower name that fits the botanical-name trend (see nature names). Hard to disentangle the HP effect from the flower-name trend.
Hermione — still #1,674
This is the Elsa paradox (see Disney names) applied to Harry Potter: the most beloved female character in the franchise is essentially unused as a baby name.
Hermione — #1,674 in 2024 (122 babies). It was not even charted in 2000.
The mechanism is clear: Hermione is so strongly associated with Emma Watson and the HP books that naming a daughter Hermione is essentially naming her after a specific fictional person. Parents who love Harry Potter often specifically avoid naming children after the main characters for this reason — it feels too costume-like.
The Greek origin (Hermes' daughter) gives Hermione a legitimate classical pedigree, but it can't overcome the franchise saturation.
Harry — from #512 to #778 (falling)
Harry — Harry Potter himself has had no positive effect on the name Harry in the US. Harry went from #512 in 2000 to #778 in 2024 — declining through the entire HP era.
Why? Several factors:
- Harry is deeply British in sound and feel; it hasn't crossed to mainstream American use
- The name was so strongly associated with the character that it felt like a direct reference
- Prince Harry (Henry, Duke of Sussex) kept the name in a royal context; the 2018 royal wedding and later public controversies complicated the name's associations
Harry is in the UK top 5. In the US, it's falling. The same franchise, two countries, opposite effects.
Ron — from #1,342 to #3,604
Ron — Ron Weasley is one of the most beloved HP characters. In 2024, there were 31 babies named Ron. Ronald is #2,126. The entire HP era has produced essentially no impact on Ron as a baby name — it already had a strong mid-century American association (Ronald Reagan, Ron Howard) and is cycling as a "dated" mid-century name, not reviving.
Draco — from #4,971 to #1,281
Draco — the villain's name is actually climbing. Draco Malfoy is the primary antagonist; Draco was essentially unused in US data (less than 10 babies) before the HP films and is now at #1,281 with 153 babies. Still very rare, but clearly HP-driven. Parents who want an HP connection but want something distinctive (rather than Luna or Lily, which are now mainstream) are choosing the Slytherin name.
Draco is also a constellation (the dragon) and an ancient Athenian lawmaker — so it has the celestial connection that helps many HP-adjacent names.
Lavender — from #5,218 to #997
Lavender — Lavender Brown is a minor HP character, but Lavender is also a botanical/color name that fits the nature-naming trend. At #997, Lavender is rare but climbing. The HP connection and the botanical trend are probably both contributing.
Names that rose independently but have HP connections
Several names at the top of the current charts have Harry Potter characters — but the HP connection isn't why they're popular:
Oliver — #3 (15,343 babies): Oliver Wood is a minor HP character (the Gryffindor Quidditch captain). Oliver's rise to #3 is entirely driven by the British vintage revival and the broader Anglosphere name trend. See vintage boy names.
Theodore — #4 (12,011 babies): Theodore Nott is a minor Slytherin character. Theodore's rise is the vintage revival, full stop. No HP connection needed.
Luna — #13: As discussed, the celestial trend is the primary driver.
The Harry Potter naming principle
Based on the data, the HP effect on names follows a specific pattern:
What works:
- Names that are unusual but not unique to HP (Luna, Lavender, Draco) — HP makes them possible; another trend makes them popular
- Villain names with an independent appeal (Draco = celestial)
- Minor character names that parents can use without the "named after Harry Potter" association
What doesn't work:
- The main characters' names (Harry, Ron, Hermione) — too strongly coded as fictional characters
- Names that feel like costumes (Dumbledore, Voldemort, Snape)
- Names that were already declining (Harry) or never established (Ron) in American culture
The Hermione paradox: The most beloved female character became the most avoided name — because loving Hermione meant you knew not to name your daughter after her.
The HP name that actually worked
If you're looking for an HP-adjacent name that has genuinely crossed into the mainstream, Luna is the answer. At #13, it's the clearest example of HP providing the initial visibility boost that a convergence of other trends (celestial, Spanish, Latin) then drove to the top 15.
