Mallon is Irish in Origin.

Mallon is a modern given name drawn from an Irish surname of Ulster, rooted in the Gaelic Ó Mealláin, “descendant of Meallán.” The personal name Meallán is a diminutive of meall, a word with layered senses in Irish - “pleasant, charming,” but also “lump, mass” or “hill” - yielding interpretive meanings such as “little pleasant one” or “little hill.” The surname is long established in Counties Armagh and Tyrone, noted in early records and associated with figures like the 17th‑century chronicler Tarlach Ó Mealláin, and echoes the memory of early saints named Meallán.

As a given name, Mallon is rare but has gained occasional use in Ireland, Britain, and the United States since the late 20th century, typically masculine but workable as unisex. Variants and related Anglicizations include Mellon, Mallin, and Mallen; the Gaelic form is Ó Mealláin. Not to be confused with Scandinavian Malin, Mallon carries a calm, earthy meaning.
