Ronnaug is Norse in Origin.

Ronnaug is the anglicized form of Norwegian Rønnaug, a feminine given name ultimately tracing back to Old Norse Rǫgnlaug (modernized as Ragnlaug). It combines regin, “the ruling powers/the gods,” with laug, “vowed, betrothed,” yielding the sense “one vowed to the gods” or “sacred promise of the gods.” Dialectal sound shifts within Norwegian produced the ø vowel and the double n; outside Norway, the diacritic is typically dropped to Ronnaug.

The name is documented in medieval Scandinavian usage and reappeared during the 19th–20th‑century Norwegian national romantic revival, though it has remained rare. Notable bearers include the Norwegian author Rønnaug Kleiva and actress Rønnaug Eggen. Variants and related forms include Rønnaug (standard Norwegian), Ronaug (simplified spelling), Rønnlaug/Ronnlaug (orthographic variant), and the Old Norse/Icelandic Ragnlaug. Ragnhild is a cognate in the same “regin-” name family but with a different second element.
