What is the meaning of the name Rhiannen ?

The baby name Rhiannen is a Female name , 3 syllables long and is pronounced /rɪˈænən/ (rih-AN-en).

Rhiannen is Welsh in Origin.

Rhiannen is a modern spelling variant of the Welsh name Rhiannon, anchored in Celtic mythology. Rhiannon appears in the medieval Mabinogion as a sovereignty and horse-associated heroine, widely linked by scholars to the older Celtic theonym Rigantona, “great/divine queen” (from Proto-Celtic rig- “kingly, royal”). The meaning thus centers on queenship, authority, and grace.

Use of Rhiannon entered broader Anglophone naming only in the 20th century, with a sharp rise after Fleetwood Mac’s 1975 song; creative spellings such as Rhiannen followed in the late 20th and early 21st centuries, especially in the UK, Australia, and North America. Close variants include Rhiannon (standard), Rhianon, Rhiannan, Rhianna, Rhianne, and Reannon; related Welsh short form Rhian (“maiden”) is sometimes used as a diminutive but has a distinct etymology. Common nicknames are Rhi, Annie, and Nonnie. Rhiannen offers a distinctive look while preserving the name’s mythic resonance.
