Rheon is in Origin.

Rheon is a rare Welsh-influenced given name that also aligns with a classical Greek root. In Wales it appears first as a surname - well known through the actor Iwan Rheon - and has only recently been adopted as a first name, largely in the U.K. The initial rh- reflects a distinct Welsh sound, lending the name a Celtic character even when used outside Wales. As a modern given name, it remains uncommon and reads contemporary, concise, and cross-cultural.

Etymologically, Rheon matches the Greek participle rhéōn (ῥέων), “flowing,” from rhéō, “to flow,” suggesting meanings such as “flowing,” “ever-moving,” or “of the stream.” Variant spellings and near-forms include Reon and Rhion; it also sits near Welsh favorites Rhian and Rhiannon (feminine) in look and sound, though not directly related. Usage skews masculine but can be unisex. Overall, Rheon offers a sleek name with a poetic, fluid meaning.
