Rhyatt is a modern American coinage that blends Wyatt with Rhett or Rhys. Wyatt itself comes from the medieval English name Wyot, from Old English elements meaning "war" and "brave", so Rhyatt borrows the sense "brave in war" along with the cowboy swagger. The name barely existed before 2017, when it jumped from number 10501 to number 3297, peaked at number 2352 in 2018 and ranks number 2443 in 2025 with 56 boys.
