Meaning & Story

A Welsh name of uncertain origin, possibly derived from a word meaning "great queen" or linked to the divine feminine in Celtic mythology.

Rhiannon is a name wrapped in mystery and magic, drawn from Welsh mythology where she is a powerful goddess associated with horses, the moon, and the Otherworld. It's a deeply poetic name that suits a pet with an otherworldly beauty or a regal, independent spirit. The name was immortalized for modern audiences by Fleetwood Mac's 1975 hit song, giving it a rock-and-roll mystique alongside its mythological roots. Rhiannon is an especially fitting name for mares, female dogs with a majestic bearing, or any pet who seems to carry a quiet, ancient wisdom. It's a name that feels both grand and intimate.
