Allistair is Scottish in Origin.

Allistair is a modern English respelling of Alistair/Alastair, the Scottish Anglicized form of Gaelic Alasdair, itself the Gaelic equivalent of Alexander. From Greek Alexandros (alexein, "to defend," + aner/andros, "man"), it means "defender of men" or "protector of humankind." The double-l spelling is a recent stylistic variation that preserves the traditional sound with a contemporary look.

The name entered Scotland in the medieval era via Latin and Norman French forms of Alexander, then Gaelicised as Alasdair and linked to Highland clans and poetry (e.g., Alasdair mac Mhaighstir Alasdair). From the 18th to 20th centuries, Anglicized spellings Alistair and Alastair spread; modern variants include Allister, Alister, and Alasdair. Nicknames include Ali, Al, Ally, Sandy, and Alec. Figures like Alastair Sim and Alistair Cooke kept the name prominent in Britain.
