Ian or Iain is a male name of Scottish Gaelic origin, which is derived from the Hebrew given name יוֹחָנָן‎ (Yohanan, Yôḥānān) and corresponds to the English name John. The spelling Ian is an Anglicization of the Scottish Gaelic forename Iain. This name is a popular name in Scotland, where it originated, as well as in other English-speaking countries. The name has fallen out of the top 100 male baby names in the United Kingdom, having peaked in popularity as one of the top 10 names throughout the 1960s. In 1900, Ian ranked as the 180th most popular male baby name in England and Wales.
