Rhoinn is Irish in Origin.

Rhoinn is a rare modern given name with layered, cross-linguistic inspiration. The initial Rh- hints at Welsh orthography, while the core -hoin(n) aligns closely with the Sanskrit name Rohin, “rising, growing; reddish,” connected to the lunar mansion Rohini in Vedic tradition. Some parents also read it alongside Gaelic favorites Rowan (“little red one”/rowan tree) and Ronan (“little seal”), making Rhoinn feel at once Celtic and pan‑Indo‑European, usually pronounced ROH‑in.

As a contemporary invention, it has scant historical record before the late 20th century and is chiefly found in Anglophone naming. Spellings and short forms include Rhoin, Roinn, Ro, and Rin; cognate or near‑variants by origin are Rohin/Rohini (Sanskrit), Rowan (Irish/Scottish), and Rhon/Rhion (Welsh). Because of its multiple etymological paths, Rhoinn can carry meanings from “to grow, to ascend” to “red‑haired, ruddy,” depending on the lineage you prefer.
