Macalaster is Scottish Gaelic in Origin.

A rare Scottish Gaelic surname turned given name, Macalaster derives from Mac Alasdair, meaning "son of Alasdair," with Alasdair the Gaelic form of Alexander (Greek Alexandros, "defender of men"). The name is rooted in the western Highlands and Isles, where Clan MacAlister - descended from Alasdair Mor, a 13th-century son of the MacDonald lineage - held territories in Kintyre and the Hebrides. As families migrated to Ulster and later across the Atlantic, the surname spread and occasionally transitioned to use as a first name.

Macalaster is the least common of several spellings; better-known variants include MacAlister/Macalister, MacAlester/Macalester, McAlister, McAllister, and the Gaelic Mac Alasdair. Related given-name forms are Alasdair, Alistair, and Alastair; Manx cognates include Callister and McCallister. Contemporary use as a baby name fits the broader Anglophone trend of surname choices, offering a rugged Highland heritage with the classic meaning "defender's son" or, by extension, "defender of men."
