Luna is the Latin word for the moon. It was also the name of the Roman goddess of the moon, the day of the week Monday is named after her (dies Lunae), the amusement park in Coney Island took the name in 1911, and one of the most quietly influential fictional characters in modern children's literature carries it. In the last two decades Luna has climbed from an unusual English choice to the 38th most popular girls' name in England and Wales in 2024, part of the fastest-rising cluster of British girls' names in a generation.
The story of how a word for a moon became a British top 40 name in twenty years is worth telling properly.

🌙 The Word That Meant Light
Luna comes directly from the Latin word lūna, which meant "the moon" and, in classical Roman religion, "the goddess of the moon." According to Etymonline, Latin luna traces back through Proto-Indo-European *leuksna-, a suffixed form of the root *leuk-, meaning "light" or "brightness." This is the same ancient root that gave English the words light, lucid, lunatic, and (via Old Church Slavonic luna and Middle Irish luan) the words for moon in almost every Indo-European language.
The core meaning is worth pausing on. Luna does not mean "moon" in the sense of a round rock in the sky. It means "the shining one," "the bright one." Latin speakers named the moon after what it did, not what it looked like. The word carries three thousand years of that specific idea: illumination in the dark.
Because the Latin day dies Lunae was the day of the moon, the same connection survives in modern languages: French lundi, Italian lunedì, Spanish lunes, and (from an older Germanic path) English Monday, which is literally "Moon-day." A girl named Luna carries the name of the day 14% of Britain wakes up dreading every week.
🏛️ The Roman Goddess Who Rode a Chariot Across the Sky
Ancient Rome personified the moon as a specific goddess, Luna, complement to the sun god Sol. According to Wikipedia's entry on the goddess, Luna was worshipped with dedicated temples on both the Aventine Hill and the Palatine Hill in Rome, and was one of the deities the historian Macrobius suggested might have been the secret tutelary protector of the entire city.
She was depicted riding a two-horse chariot called the biga, wearing a crescent moon crown, and driving across the night sky. In Roman art she was often paired with her brother Sol in his four-horse chariot, the two together representing the full daily and nightly cycle. She was also considered one aspect of a triple Roman goddess (diva triformis), together with Diana (the huntress) and Proserpina (queen of the underworld) or Hecate (goddess of witchcraft).
Luna's Greek equivalent was Selene, daughter of the Titans Hyperion and Theia, sister of Helios (the sun) and Eos (the dawn). Selene's most famous myth was her love for the mortal shepherd prince Endymion. She fell in love with him while watching him sleep, and asked Zeus to grant him eternal youth and eternal sleep so she could visit him every night. The two-thousand-year mythological tradition around Luna and Selene has quietly shaped every modern association with the name: femininity, mystery, quiet devotion, watching from above.
🎼 The Debussy Piano Piece Everyone Recognises
In 1890, the French composer Claude Debussy wrote a short piano piece called "Clair de Lune" (literally "moonlight"), inspired by an 1869 poem of the same title by the poet Paul Verlaine. It is now one of the most-recognised pieces of classical music ever composed, appearing in dozens of Hollywood films from Ocean's Eleven to Twilight. Every time it plays, the word Luna slips quietly back into cultural circulation, even for listeners who do not consciously realise they are hearing it.
🪄 The Fictional Girl Who Made Luna a Real Name
Luna was almost unknown as an English girls' first name until the year 2003. That is the year J.K. Rowling published Harry Potter and the Order of the Phoenix, the fifth novel in the Harry Potter series, and introduced a Ravenclaw student called Luna Lovegood.
Rowling has said in interviews that she originally drafted the character under the name Lily Moon, which appears briefly in Harry's Sorting Ceremony in book one. She later renamed her Luna and described her as the "anti-Hermione," a girl who arrives at beliefs through faith and intuition rather than logic and evidence. Luna Lovegood became one of the most beloved characters in the entire seven-book series.
When the films were cast, Warner Bros. held an open audition across the UK and Ireland for the role, and received applications from around 15,000 girls. The role went to an unknown Irish teenager called Evanna Lynch (born 16 August 1991 in Termonfeckin, County Louth). She played Luna in four Harry Potter films between 2007 and 2011. Rowling reportedly described Lynch's portrayal in a single word: "perfect."
Luna, as a first name in English, essentially begins here. Baby-name analysts recorded a sharp uptick in the name across the UK and US from 2004 onwards, the year after Luna Lovegood first appeared in print. The film adaptations accelerated it further. By 2015 Luna was inside the US top 100 for the first time. By 2024 it had reached tenth place in the US, and thirty-eighth in the UK. Very few characters in modern literature have moved a name up the international charts this dramatically.
📈 Why Luna Fits This Exact Moment in British Naming
Luna's climb up the UK charts is not just a Harry Potter effect. It is part of a broader British trend that includes Aurora, Nova, Willow, Ivy, and Delilah, all celestial or botanical names that have jumped up the charts together in the last decade. According to Mumsnet's analysis of the ONS 2024 data, Luna is currently 38th and rising, part of a cluster of what commentators have started calling "cosmic girls' names."
British parents in the 2020s have been reaching for names that feel timeless but also modern, familiar but distinctive, meaningful but not tied to a specific religion or family tradition. Luna fits all four criteria unusually well. It is Latin (classical), it is short (modern), it means something concrete (the moon), and it belongs to no particular culture or faith tradition. This is why celebrity parents have adopted it enthusiastically.
⭐ The Lunas Who Left Their Mark
- Luna (Roman goddess), divine embodiment of the moon in Roman religion, worshipped with temples on the Aventine and Palatine Hills of Rome from at least the 3rd century BC.
- Luna Simone Stephens (b. 14 April 2016), daughter of American singer John Legend and model and cookbook author Chrissy Teigen. Her birth in 2016 pushed the name sharply up the US charts almost overnight.
- Luna Thurman-Busson (b. 15 July 2012), daughter of actress Uma Thurman and French financier Arpad Busson.
- Evanna Lynch (b. 16 August 1991), Irish actress, played Luna Lovegood in four Harry Potter films between 2007 and 2011, chosen from around 15,000 girls at open audition.
- Luna Blaise Boyd (b. 1 October 2001), American actress, star of NBC's Manifest (2018 to 2023).
- Luna Lovegood (fictional), Ravenclaw student in J.K. Rowling's Harry Potter novels (2003 to 2007), one of the most-beloved characters in modern children's literature.
💙 Living With the Name
Luna is two syllables and rarely shortened. When it is, the affectionate forms are Lu, Lulu, or occasionally Loonie in playful family use. Most families simply use the full name. For UK parents, one small practical consideration: lunatic comes from the same Latin root, and any child called Luna will hear the joke at some point in her school life. It is worth being prepared for.
For middle names, Luna pairs beautifully with slightly longer options that give it a more formal counterweight: Luna Grace, Luna Rose, Luna Beatrice, Luna Charlotte, and Luna Elizabeth all read cleanly. As a sibling name it sits comfortably beside other current UK celestial and botanical names: Aurora, Nova, Ivy, Willow, Lily, and Iris for sisters; Orion, Atlas, Arthur, Theodore, and Oscar for brothers.
✨ Should You Choose Luna?
Luna is short, warm, internationally recognisable, mythologically rich, and unusually well-suited to the current British naming moment. Its meaning is unusually simple ("the moon") and unusually poetic. Its main practical drawback is the lunatic connection, which any Luna will hear about, though modern British children generally take name jokes in stride. Its second drawback is popularity: at thirty-eighth and climbing, Luna is common enough that a daughter born today may share the name with one or two others in her school year. If either concerns you, the Greek equivalents Selene or Selena offer the same meaning in less common forms. Otherwise, Luna is one of the strongest classical girls' names available in English today, and there are worse legacies to give a child than a name meaning "the shining one."
