McAlister
A Scottish and Irish surname meaning “son of Alister,” with Alister ultimately tracing back to Alexander.
The #3,078 most common surname in the United States (2010 Census) — about 1 in every 26,468 Americans shares it.
Etymology
McAlister is a patronymic surname: the prefix Mac means “son of” in Gaelic. The name is formed from Alister, a Gaelic form ultimately related to Alexander, so the literal sense is “son of Alister” or “son of Alexander.” Historical notes in the sources explicitly gloss it that way, and they also show many spelling forms built around the same Gaelic name.
History
The name is well established in Scottish Highland and Irish usage, and the sources place bearers among Highland families such as the MacAlesters of Tarbert and MacAlister of Glenbarr in Argyll. Spellings have varied a lot over time, including MacAlister, MacAlester, MacAllister, MacCallister, and shortened forms like Callister and Lester. In older records, the form often reflects local pronunciation more than fixed spelling.

Fun fact
Some older surname collections treat McAlister and McAllister as part of the same broad Alexander-name family, which is why so many “Mac-” and “Mc-” spellings cluster together.
