Alastair is in Origin.
Alastair is the Anglicised Scottish form of Gaelic Alasdair, the Celtic rendering of Alexander. Through Greek Alexandros - from alexein “to defend” + andros “man” - the name carries the meaning “defender of men,” sometimes expanded as “protector of mankind.” In Scots and Scottish Gaelic tradition it functions as a distinctly Highland expression of the pan-European Alexander.
Documented among medieval Scottish nobility and clan leaders, the name persisted in Scotland and later gained wider British use, seeing 19th‑century revival and steady 20th‑century visibility via figures such as actor Alastair Sim, novelist Alastair MacLean, and Prince Alastair of Connaught. Variant spellings include Alasdair (Gaelic), Alistair, Alister, and Alaster; short forms range from Al and Alec to the Scots Sandy. Cognate equivalents abroad include Alexander, Alexandre, Alessandro, and Alejandro.
