Tiernon is Irish in Origin.

Tiernon is a modern Anglicized given name ultimately from Irish Gaelic Tighearnán/Tiarnán, a diminutive of tighearna “lord, master.” The sense is “little lord,” often interpreted as “noble” or “lordly.” The name’s affectionate -án ending marks either youth or endearment, a common feature in early Irish personal names. English speakers typically say TEER-nən/TEER-non, though regional Irish usage varies.

In Ireland the name appears in annals from the early medieval period, borne by clerics and chieftains; a prominent figure is Tighearnán Ó Ruairc (Tiernan O’Rourke), 12th‑century king of Bréifne. Tiernon represents a contemporary spelling variant of Tiernan, adopted in the late 20th and early 21st centuries as a distinctive yet authentic choice. Related forms include Tiernan, Tiarnán (standard modern Irish), Tighearnán (classical Gaelic), and the Scottish Ternan; surnames MacTiernan/McKiernan and Tierney (Ó Tighearnaigh) derive from the same root.
