MacTàmhais is the Scottish Gaelic form of the surname McTavish. Both names derive from the Gaelic personal name Tàmhas, which itself is the Gaelic version of Thomas, a name of Aramaic origin meaning "twin." The prefix Mac means "son of," so the full meaning is "son of Tàmhas" or "son of Thomas."
While the anglicized McTavish is more widely known, MacTàmhais preserves the original Gaelic spelling and pronunciation. The name is primarily associated with Scottish heritage and likely originated in the Highlands, where Gaelic was the dominant language until recent centuries. Due to migration and the anglicization of names, many bearers of this name now use the Mc spelling.
Notable bearers of the related McTavish name include John McTavish (c. 1775–1815), a fur trader and explorer in Canada, and Duncan McTavish (1703–1770), a prominent Scottish timber merchant. In literature, the name appears in the character Dr. Hector MacTavish Innes from Sir Walter Scott’s novels. The legacy of the name remains strong in Scotland and the Scottish diaspora.
