Blain is Irish, Scottish in Origin.

Blain is a Scottish given name and surname, an Anglicized form of Old Irish Bláán, borne by a 6th–7th‑century monk-bishop venerated as St Blane on Bute and in Strathearn (cf. Dunblane). The underlying root is Old Irish blá “yellow, sallow,” with the diminutive –án, yielding the sense “little yellow/fair one,” often interpreted as “fair‑haired.” The name entered Scots and English through saintly cult and local surnames.

In use as a personal name since medieval Scotland, it re-emerged in the 19th‑century revival of Celtic names and the surname‑as‑given‑name trend, gaining wider North American currency in the 20th century. Blaine is now the dominant spelling; Blane and Blayne are common variants, while Blain remains the sparsest modern form. Though traditionally masculine, it sees occasional unisex use. Note that English blain meaning “blister or swelling” is an unrelated word‑form and not the source of the given name.
