The name Tobin has a dual origin: it is of Norman-French/Irish origin, derived from Saint-Aubin and Anglicized from the Gaelic Ó Tóibín and also has a Hebrew origin related to the name Tobias. The Irish version is associated with a powerful family that settled in counties Tipperary and Kilkenny after the Norman invasion, while the English version is often a diminutive of Tobias, meaning "God is good".
