Rhiun is a modern, Welsh‑influenced coinage built on the language’s distinctive rh‑ onset and ‑un ending. It sits between Rhian (from Welsh rhiain, “maiden”) and Rhun, a medieval Welsh male name borne by princes such as Rhun ap Maelgwn, whose meaning is debated but often glossed “great, mighty.” Not attested in traditional Welsh records, Rhiun has no fixed historical meaning, yet it echoes themes of royalty and strength also heard in the mythic name Rhiannon (“great queen”).

Usage is very rare and recent, typically as a gender‑neutral choice. Pronunciations vary: REE‑ən or REE‑oon; in Welsh, rh is a voiceless r, approximated in English as an aspirated r. Variants and related forms include Rhian, Rhion, Rhyun, Rhioun, and streamlined Riun or Rion; possible nicknames are Rhi or Rue.
