Generate names for dragons in the Welsh tradition: Welsh-word names like Tanllwyth, Draig Ddu and Gwiber y Llyn, English epithets tied to real places like The Red Wyrm of Eryri, and legend names such as Emrys Ember-Eye. The few attested dragons are labeled; the rest are newly made.

About Welsh dragon names

Wales has one of the world's best-known dragons on its flag and almost no named dragons in its stories. Y Ddraig Goch, the red dragon, is a description, not a personal name. In the most famous tale, first told in the ninth-century Historia Brittonum and set at Dinas Emrys in Eryri, a red dragon and a white one fight beneath a king's unfinished fortress, and neither is named. Folk tales add the gwiber, a winged serpent known only by its haunt, such as the Gwiber of Penmachno.

The names with a note in parentheses are the attested ones; everything else is newly made. About half are built from plain Welsh words: single words such as Tanllwyth (a blaze), Mellten (a lightning bolt) and Taran (thunder), draig with a color, as in Draig Ddu, the black dragon, and place forms like Draig y Mynydd, dragon of the mountain. Draig is a feminine noun, so the word after it softens (coch becomes goch), and after the article it softens itself: y ddraig.

The rest are English epithets tied to real mountains, lakes, rivers and castles, such as The Red Wyrm of Eryri, names from the Mabinogion and Welsh Arthurian legend offered as names for a dragon, heraldic names like Dragon Passant, and friendly mascot names for St David's Day.

How to choose Welsh dragon names

  • Check the mutation before you print a name. After draig a describing word softens: Draig Goch, Draig Wen, Draig Ddu, Draig Las. With the article the noun softens too, which is why the flag is Y Ddraig Goch.
  • Pick the kind of beast first. A draig is the four-legged, winged dragon of the flag, a gwiber is the winged serpent of the folk tales, and sarff simply means serpent. The afanc of Welsh lakes is a different monster and is not in this list.
  • For a story or campaign set in Wales, a place name does half the work. The Tryfan Watcher or Draig Cadair Idris tells readers where the lair is, so look for the peak, lake or river nearest your setting.
  • For a mascot, a school project or St David's Day on March 1, short friendly names work best: Tân Bach, Sbarc, Cennin or Draig Fach Goch.
  • Keep the accents when you copy a name. In Welsh the circumflex changes the word: tân is fire, while tan means until or under, so Draig Dân needs its mark.

Frequently asked questions

What is the Welsh dragon called?

The red dragon of the flag is Y Ddraig Goch, which simply means the red dragon. It is a description, not a personal name, which is why this generator offers names such as Tanllwyth, Draig y Mynydd and Emrys Ember-Eye for a dragon of your own. The flag, a red dragon on a green and white field, was officially recognized in 1959.

Are these real dragon names from Welsh legend?

Only a handful. The entries with a note in parentheses, such as The Red Dragon of Dinas Emrys (legend) and The Gwiber of Penmachno (folk tale), come from tradition. Welsh legend names almost no dragon, so everything else is newly made from Welsh words, real place names and heraldry. Names like Emrys, Idris and Ceridwen belong to figures of legend and are offered here as names for a dragon, not as dragons from the stories.

What is a gwiber?

In Welsh folk tales a gwiber is a winged serpent, often translated as wyvern, while in everyday Welsh the same word means a viper. Tales place one at Penmachno and another at Newcastle Emlyn. The list uses the word in Welsh forms like Gwiber y Llyn and Gwiber Goch and in English ones like Gwiber of Llyn y Fan Fach.

How do you pronounce draig and Y Ddraig Goch?

Draig is one syllable, close to the English word dry with a hard g on the end. In Y Ddraig Goch the y sounds like uh, the dd is the th of the word this, and the ch is the sound at the end of the Scottish word loch.
