Blainey is Irish, Scottish in Origin.

Blainey is a modern pet-form and variant of Blaine, which traces to Old Irish Bláán, a diminutive of blá meaning “yellow, blond” or “fair.” The name entered Scots and English via the medieval Saint Bláán (St. Blane), a 6th–7th‑century bishop associated with the Isle of Bute, and later appeared as both a given name and a surname in Scotland and Ireland before gaining wider Anglophone use.

As a given name, Blainey adds a gentle -y/-ie flourish common in contemporary English diminutives, giving it a softer, often feminine-leaning feel while remaining technically unisex. It remains rare, seen mainly in the United States, Canada, and Australia, where Blainey also exists as a surname. Core variants and cognates include Blaine, Blain, Blayne, Blaney, and the surname forms Blayney/Blaney; creative spellings like Blainy or Blaynie occur. The meaning “little blond/fair one” suits the diminutive shape, and informal nicknames may include Blay or Lainey.
