Smyth is an Anglo-Irish surname and given name, derived from the Middle English word 'smith', which originally referred to someone who worked as a blacksmith. It is believed to have originated from the Old Norse word 'smiðr' meaning 'smith'. The name became common in Ireland due to Norman influence during the medieval period, with many variations such as Smith, Smythe, Smithe, and McSmith existing today. In some cases, Smyth can also be an anglicized form of the Irish surname Ó Smyth, which is derived from the Gaelic word 'smiodh' meaning 'peaceful'. The name has been used as a given name more frequently in recent times, particularly among English-speaking countries.
In 2019 alone, six newborns were named Smyth, making it an annual total of six births with this name.
