The name Erwan is a boy's name of Breton origin meaning "yew; great talent; dragon".

Also spelled as Erwann, this airy yet rugged sounding choice was a Top 100 name in France during the 2000s and remains in the Top 300 today. Considered the Breton form of Yves or Ivo, meaning "yew", other sources also suggest it may derive from the Breton Eudon ("great talent") or from aerouant which translates to "dragon". 
 
Said roughly as AYR-WAHN, but with a guttural "r", notable bearers include TV and Youtuber chef Erwan Heussaf, footballer Erwan Regulus, poet and writer Erwan Berthou, and chef and content creator Erwan Botrel.
