Clan MacAlister is a Scottish clan that originates from the western Highlands, particularly associated with the region of Argyll. The clan's name is derived from the Gaelic "Mac Alasdair," meaning "son of Alasdair," with Alasdair being the Gaelic form of Alexander. Historically, the clan has been linked to the MacDonald clan and played a role in the turbulent history of Scotland, particularly during the Scottish Wars of Independence. The clan's motto is "Fortis et fidelis," which translates to "Brave and faithful," reflecting their values and heritage.
