Walsh is a common Irish surname, meaning "Briton" or "foreigner", literally "Welshman" or "Wales", taken to Ireland by soldiers from Britain, namely Cambro-Norman/Welsh, Cornish and Cumbrian soldiers during and after the Norman invasion of Ireland. It is most common in County Mayo and County Kilkenny. It is the fourth most common surname in Ireland, and the 265th most common in the United States. There are variants including "Walshe", “Welch”, "Welsh", "Brannagh", and the Irish "Breathnach". Walsh is uncommon as a given name. The name is often pronounced "Welsh" in the south and west of the country. In Great Britain, Guppy encountered the name only in Lancashire. It is the surname of the Barons Ormathwaite.

Ciarán Walsh (b. 1980 in Carlow, Ireland) is a contemporary Irish artist currently living and working in Berlin.
