Tierrney is Irish in Origin.

Tierrney is a modern respelling of Tierney, the Anglicized Irish surname Ó Tighearnaigh, meaning “descendant of Tighearnach.” The personal name Tighearnach (also Tigernach) comes from Old Irish tighearna, “lord, master,” giving the sense “lordly” or “noble.” Pronounced TEER-nee, the double‑r form is rare but clear to English readers.

The surname arose among several unrelated Irish families, notably in Meath, Tipperary, Clare, and Galway, and appears in medieval annals; the underlying given name is associated with Saint Tigernach of Clones. As a given name, Tierney/Tierrney gained late‑20th‑century use in the U.S., Britain, and beyond, used for all genders with a slight female tilt in America, helped by the visibility of actress Gene Tierney. Variants include Tierney (standard), Tierny, and Tyrney; Gaelic forms Tighearnach/Tigernach occur in historical sources. Related but distinct are Tiernan (Ó Tighearnáin) and McTiernan.
