Welsh names carry something most modern names simply don’t: a living connection to a language that has been spoken continuously for over 1,500 years. These are not names borrowed from Latin or Norman French and re-dressed as Welsh, they grew from the Welsh language itself, from the landscapes of Wales, from its mythology, its saints, and its poets. If you are drawn to names with genuine depth and a sound unlike anything else in the English-speaking world, Welsh names deliver exactly that.
Pronunciation is half the story with Welsh names, so each entry below includes a plain-English phonetic guide. Welsh spelling is consistent once you know the rules, “dd” sounds like the “th” in “the,” “ll” is a voiceless lateral fricative (breathe out over your tongue while saying “l”), “w” and “y” are vowels as often as they are consonants, and “f” sounds like “v.
Classic Welsh Boys’ Names
These are the names that have anchored Welsh naming culture for centuries, carried by princes, saints, and poets. Many are still in the top names in Wales today.
Rhys
Pronounced HREES (the “rh” is a breathy, voiceless r). From an Old Welsh word meaning “enthusiasm” or “ardor.” It is one of the oldest and most enduring Welsh names, borne by several medieval Welsh rulers, and has crossed over into mainstream English-speaking use without losing any of its edge.
Owain
Pronounced OH-wine. The Welsh form of a name related to the Latin Eugenius, meaning “well-born,” though its roots in Welsh legend run far deeper than the Latin borrowing. Owain Glyndwr, the last native Prince of Wales, is the most famous bearer and a towering figure in Welsh history.
Caradoc
Pronounced kuh-RAD-ok. The Anglicized form of the Welsh Caradog (kuh-RAH-dog), from a Celtic root meaning “beloved” or “amiable.” It was the name of a legendary British king who resisted Roman invasion, giving it genuine heroic weight.
Emrys
Pronounced EM-ris. A Welsh form derived from the Latin Ambrosius, meaning “immortal.” In Welsh legend, Emrys is one of the names of Merlin, specifically Myrddin Emrys, making this one of the most mythologically loaded names on this list.
Geraint
Pronounced GEH-rynt (the final “t” is soft). An ancient Welsh name of uncertain but likely Celtic origin, borne by a warrior hero in the Arthurian tales and in the early Welsh poem “Geraint fab Erbin.” It has a strong, clipped sound that wears well in any era.
Hywel
Pronounced HOW-el (the “hw” is a breathy h-w sound). Meaning “eminent” or “prominent.” Hywel Dda, Hywel the Good, was a tenth-century Welsh king famous for codifying Welsh law, which gives the name real historical gravitas.
Llywelyn
Pronounced lhloo-EL-in (that opening “ll” is the voiceless Welsh lateral). The meaning is debated but likely relates to “leader” or contains an element meaning “lion.” Two princes of Wales bore this name, making it the most dynastically significant Welsh name of the medieval period.
Idris
Pronounced ID-ris. From Welsh elements meaning “ardent lord” or “fiery lord.” Cadair Idris, a dramatic mountain in Snowdonia, is named for a legendary giant of this name, giving it a powerful geographic anchor in Welsh culture.
Cai
Pronounced KYE. The original Welsh form of Kay, the name of one of Arthur’s chief knights in the Mabinogion. Simple, ancient, and genuinely Welsh, it avoids the over-familiar feel of the English Kay or Kai while keeping the same clean sound.
Bedwyr
Pronounced BED-wir. The original Welsh name of the knight known in English as Bedivere, Arthur’s most loyal companion and the one who returned Excalibur to the lake. It is rare today, which makes it all the more striking.
Classic Welsh Girls’ Names
Welsh girls’ names range from the lyrical and floral to the fierce and mythological. These are the names that Welsh families have returned to across generations.
Seren
Pronounced SEH-ren. Meaning “star” in Welsh. It has become one of the most popular girls’ names in Wales over the past two decades, and for good reason: it is easy to pronounce, instantly beautiful, and carries a meaning that feels both ancient and modern.
Rhiannon
Pronounced hree-AN-on. From an Old Celtic root, possibly derived from a word meaning “great queen” or related to a divine figure. Rhiannon is the enchanting, horse-riding queen of the Mabinogion, one of Welsh mythology’s most complex and compelling characters. Fleetwood Mac introduced the name to a global audience in 1975.
Nia
Pronounced NEE-ah. The Welsh form of Niamh, from Old Irish meaning “brightness” or “radiance.” It is short, strong, and cross-cultural enough to wear well beyond Wales, while still being rooted in the Celtic world.
Cerys
Pronounced KEH-ris. From the Welsh word carumeaning “to love,” so the name carries the sense of “love” or “beloved.” Singer Cerys Matthews of Catatonia brought it to wider attention in the 1990s, but it has deep roots in Welsh naming tradition.
Morfudd
Pronounced MOR-vith (the “dd” makes a “th” sound). A name of Old Welsh origin, connected to a root meaning “maiden” or “great maiden.” It was borne by the beloved of the fourteenth-century Welsh poet Dafydd ap Gwilym, cementing its place in Welsh literary history.
Dwynwen
Pronounced DWIN-wen. Meaning “she of pure/white waves” or “blessed wave.” Saint Dwynwen is the Welsh patron saint of lovers, and January 25 is Dydd Santes Dwynwen, the Welsh equivalent of Valentine’s Day. This name has tremendous cultural weight in Wales and is almost entirely unknown outside it.
Angharad
Pronounced ang-HAR-ad. From Welsh elements meaning “much loved” or “free from shame.” It appears in the Mabinogion as the name of a beautiful noblewoman and has been a steadily used Welsh girls’ name for centuries. Long and musical, it rewards the effort of learning it.
Gwenllian
Pronounced gwen-LHLEE-an. From Welsh elements meaning “white” or “fair” and “linen” or “flaxen.” Gwenllian ferch Gruffudd was a twelfth-century Welsh princess who led troops into battle, making this one of the most historically charged names in the Welsh canon.
Blodeuedd
Pronounced blo-DAY-eth. From the Welsh word for “flowers” or “flower-face.” In the Mabinogion, Blodeuedd is a woman conjured from flowers by magic, a haunting and complex figure. The name is rare and challenging, but entirely genuine.
Elan
Pronounced EH-lan. A Welsh name connected to the River Elan in mid-Wales, with roots in Old Welsh meaning “fawn” or “young deer.” It is gentle, short, and usable far beyond Wales while keeping a distinctly Welsh character.
Welsh Saints’ Names
Wales has a remarkable tradition of local saints, and many Welsh names come directly from this tradition. These names were carried by the founders of Welsh churches and monasteries and remain in use today.
Dewi
Pronounced DEH-wee. The Welsh form of David, and the name of Saint David, the patron saint of Wales. Dewi Sant’s feast day on March 1 is the Welsh national day. This is the quintessential Welsh saints’ name, and it wears lightly as a given name for boys.
Brynach
Pronounced BRIN-akh. An early Welsh saint’s name, borne by a fifth-century monk venerated in Pembrokeshire. The root is uncertain but may be related to a word for “hill.” It is genuinely rare and entirely authentic.
Cadfan
Pronounced KAD-van. From Welsh elements meaning “battle” and “peak” or “summit.” Saint Cadfan was a sixth-century Welsh saint who founded the monastery on Bardsey Island, one of the holiest sites in medieval Wales. Strong and underused.
Tysilio
Pronounced tuh-SIL-ee-oh. A seventh-century Welsh prince who became a monk and saint, venerated across Wales and Brittany. The name is rare enough to be genuinely distinctive while carrying serious historical roots.
Non
Pronounced NON. The name of Saint Non, the mother of Saint David, making her one of the most venerated women in Welsh Christianity. Short, strong, and unusual outside Wales, it has been quietly used as a girls’ name in Welsh families for centuries.
Melangell
Pronounced mel-ANG-eth. A sixth-century Welsh saint, patron of animals and wild places, whose shrine in Montgomeryshire remains a place of pilgrimage. The name has a soft, ethereal sound that belies its considerable age.
Names from Welsh Mythology
The Mabinogion and other early Welsh texts are full of vivid, real names that have never quite made it into mainstream use outside Wales. These are some of the best of them.
Branwen
Pronounced BRAN-wen. From Welsh elements meaning “white raven” or “blessed raven.” Branwen is one of the most tragic and powerful figures in the Mabinogion, a queen whose story spans Wales and Ireland. The name is both beautiful and loaded with literary meaning.
Arianrhod
Pronounced ar-ee-AN-hrod. Meaning “silver wheel” or “silver disc,” likely a reference to the moon. Arianrhod is a powerful, ambiguous figure in Welsh mythology, and the name has attracted attention among those drawn to celestial and mythological names.
Pryderi
Pronounced pruh-DEH-ree. From a Welsh word meaning “care” or “anxiety,” though in the mythology Pryderi is anything but anxious, he is the central hero of three of the four branches of the Mabinogion. A genuinely rare name with real mythological pedigree.
Manawydan
Pronounced man-ow-WI-dan. One of the great figures of the Mabinogion, a wise and steadfast character. The name is related to the sea god Manannan of Irish mythology, pointing to deep Celtic roots. Long and unusual, it is for committed Welsh-name enthusiasts.
Ceridwen
Pronounced keh-RID-wen. The name of the enchantress and keeper of the cauldron of inspiration and knowledge in Welsh mythology. Its meaning is debated but likely contains the element cerdd (poetry, craft) and gwen (white, blessed). It is the name of a true mythological heavyweight.
Taliesin
Pronounced tal-ee-EH-sin. Meaning “shining brow.” Taliesin was a sixth-century Welsh bard whose work survives in the Book of Taliesin, one of the oldest manuscripts in the Welsh language. He also appears as a transformed figure in the legend of Ceridwen. It is a rare name with extraordinary poetic credentials.
Welsh Nature and Place Names Used as Given Names
Wales has a tradition of drawing given names from its landscape, rivers, and geography. These names are used by real people, not just pulled from maps.
Afon
Pronounced AV-on. Meaning “river” in Welsh. It has been used as a given name, particularly for boys, and carries the simplicity of a word-name with a very distinctly Welsh sound.
Bryn
Pronounced BRIN. Meaning “hill” in Welsh. Short, strong, and easy for non-Welsh speakers to pronounce, Bryn has crossed over into wider use as both a boys’ and girls’ name while keeping its Welsh identity firmly intact.
Glyn
Pronounced GLIN. From the Welsh word for “valley.” It has been a quietly steady Welsh given name for boys for generations, related to the place-name element that appears in Glyndwr and many Welsh place names.
Nant
Pronounced NANT. Meaning “brook” or “stream” in Welsh. Used occasionally as a given name, it is one of the most elemental and quietly beautiful Welsh word-names available.
Modern Welsh Names Still Rooted in Tradition
These names are newer in their current form but built on genuine Welsh linguistic and cultural roots. They are not inventions, they follow the internal logic of the Welsh language and have real usage in Wales today.
Carys
Pronounced KAR-is. Like Cerys, derived from the Welsh root carumeaning “love.” It is one of the most successful Welsh exports of the past 30 years, used widely across the English-speaking world while remaining distinctly Welsh in sound and feel. Actress Carys Zeta Douglas, daughter of Catherine Zeta-Jones, put it on the global map.
Macsen
Pronounced MAK-sen. The Welsh form of Maximus. The legend of Macsen Wledig, a Roman emperor who dreams of Wales, is one of the key stories in the Mabinogion. This name is a confident, striking alternative to the currently very popular Maxim or Max.
Aled
Pronounced AH-led. Derived from a Welsh river name, the Afon Aled in Conwy. It has been a popular boys’ name in Wales for decades, perhaps best known internationally through singer Aled Jones. Warm, accessible, and genuinely Welsh.
Ffion
Pronounced FEE-on. From the Welsh word for “foxglove,” the flower. It became widely known in the UK when Ffion Hague, wife of politician William Hague, brought it to public attention in the late 1990s. Delicate and distinctive, and far less common than it deserves to be outside Wales.
Catrin
Pronounced KAT-rin. The Welsh form of Catherine, from the Greek Aikaterine. It has been used in Wales since the medieval period and is one of the most natural entry points into Welsh naming for families who want something familiar but distinctly Welsh.
Bethan
Pronounced BETH-an. A Welsh diminutive form of Elizabeth, used as a full given name in its own right. It is warm and approachable, a genuine Welsh name that requires no explanation for English speakers while still belonging completely to Wales.
Rhodri
Pronounced HROH-dree. From Welsh elements meaning “wheel” and “ruler”, so roughly “wheel-king” or “ruler of the circle,” likely a reference to a crown. Rhodri Mawr (Rhodri the Great) was a ninth-century King of Gwynedd. It is a strong, regal name that deserves far more attention outside Wales.
Nerys
Pronounced NEH-ris. Possibly from the Welsh root nermeaning “lord” or “chief,” giving it the sense of “lady” or “noblewoman.” It gained wider recognition through the character Nerys Hughes in the British television series “The Liver Birds.” Quietly elegant and underused.
How to Choose a Welsh Name
The most important first step is deciding how much pronunciation complexity you are comfortable with. Names like Bryn, Nia, Rhys, and Seren are immediately accessible to English speakers. Names like Llywelyn, Gwenllian, or Blodeuedd require a real commitment to learning Welsh phonetics, and that is not a reason to avoid them, but it is something to go in with eyes open about.
Think about where the name will live. A child growing up in Wales will wear Dwynwen or Angharad without a second thought. A child growing up in Sydney or Chicago will spend a lifetime spelling it out and offering pronunciation guides. That is not necessarily a burden, many people love having a name that is a conversation starter and a piece of cultural identity they carry everywhere. Just make the choice deliberately.
Consider the meaning and the mythology. Welsh names carry extraordinary stories: saints who founded monasteries on cliff-top islands, warrior queens who rode into battle, enchantresses who kept cauldrons of inspiration. If the name you choose comes with one of those stories, learn it. Knowing that Gwenllian was a twelfth-century warrior princess, or that Dwynwen is the Welsh patron saint of lovers, makes the name richer for everyone who asks about it.
Finally, do not worry about “earning” a Welsh name through ancestry. The Welsh language and its naming tradition have always been generous. What matters is that you choose the name with real knowledge of what it carries and genuine respect for where it comes from.
Welsh names reward the effort. There is no other naming tradition quite like it, ancient, musical, mythologically dense, and still very much alive. Whether you land on something as accessible as Seren or as deep-cut as Taliesin, you are connecting a child to one of Europe’s oldest living literary and linguistic traditions. That is worth every patient pronunciation lesson.
