Meaning & origin

Rheannon is a modern respelling of the Welsh mythological name Rhiannon, first recorded in the United States in 1976. It reached its peak usage the very next year, in 1977, but has never entered the top 1,000 names. The name's trajectory has been stable, with only a handful of births annually, and it has not seen a revival in later decades. No states recorded enough births for Rheannon to appear in top state lists, reflecting its extremely rare, niche appeal. As a creative variant of a name with deep Welsh roots, Rheannon offers parents a distinctive spelling while maintaining a connection to Celtic tradition.

Rheannon is a modern respelling of the Welsh name Rhiannon, itself derived from the Old Celtic *Rigantona, meaning 'great queen'. In Welsh mythology, Rhiannon is a prominent figure associated with horses and the otherworld. The spelling with 'Rhea-' likely reflects influence from the Greek name Rhea or simply a phonetic variant. This spelling emerged in the United States in the 1970s alongside other creative respellings.
