Taggart is an Irish and Scottish surname from Mac an tSagairt, meaning "son of the priest."
Taggart is a surname of Scottish Gaelic origin, anglicized from *Mac an t-Sagairt*, meaning "son of the priest" — a family designation that likely arose from a hereditary ecclesiastical role in medieval Celtic Christianity, where priestly functions sometimes passed within clans. It entered English records largely through Scotland and Ulster, where Gaelic-speaking populations encountered the Anglophone administrative machinery of the British state and needed their names rendered into a new alphabet.
The name carries the rough, wind-swept sound of the Scottish Highlands, with its hard consonants suggesting granite and heather rather than courtly refinement. As a given name, Taggart is rare and almost exclusively a transfer from surname to first name, a practice with deep roots in Anglo-American naming culture. The name gained its widest cultural footprint through *Taggart*, the long-running Scottish television crime drama that aired from 1983 to 2010 on ITV, following the gruff Glasgow detective Jim Taggart — a character so iconic that the show continued under his name even after actor Mark McManus died in 1994.
That cultural association gives the name a tenacious, no-nonsense quality. For parents drawn to strong, distinctly Celtic surnames worn as first names, Taggart occupies unusual territory: immediately recognizable yet genuinely uncommon as a given name, with a lineage rooted in sacred vocation.
