MacFarlane is a Scottish surname, a variant spelling of McFarlane. Both forms derive from the Scottish Gaelic MacPhàrlain or the Irish Gaelic Mac Pharlain, meaning "son of Parthalán." The name Parthalán is the modern Irish form of Partholón, which ultimately traces back to the name Bartholomew. Origin and Meaning Like other "Mac-" and "Mc-" surnames, MacFarlane indicates patrilineal descent. The Gaelic prefix means "son of" or "descendant of," tying the bearer to the personal name Parthalán/Partholón. The name Partholón appears in Irish legendary history rather than everyday usage: the Book of Invasions, an 11th-century compilation, describes Partholón as the leader of the first settlers to arrive in Ireland after the biblical flood, although his colony was brief, all perishing from disease. An even earlier mention appears in the ninth-century History of the Britons, where the name is given as Partholomus. Scholars now view Partholón as a borrowed form of the Biblical-Aramaic name Bartholomew, and indeed the etymological chain shows its path: from Bartholomew to Partholomus, then to Partholón, Parthalán, and into the Gaelic surname MacPhàrlain/MacFarlane. Notable Bearers The surname spread among Scottish families, particularly in the Highlands, and gained prominence in various fields. While no specific famous bearers are recorded in standard reference works for MacFarlane as used today, the variant shares its historical legacy with McFarlane, a name held by numerous individuals in Scottish history, including clan chiefs, politicians, and artists. Distribution and Variants In the United States, MacFarlane is less common than its alternative forms.

Related names include the variant spellings MacFarland and McFarland (both Scottish and Irish), as well as the standard McFarlane.
