Meaning & Origin
A diminutive of the male given name Thomas, also used as a formal male given name.
Tom is a boy's and girl's baby name of Hebrew origin, a short form of Thomas, meaning 'twin.' While Thomas has ranked in the U.S. top 20 for well over a century, Tom functions as both a standalone name and an enduring nickname — one of those rare short names that carries enormous cultural weight.
From Tom Sawyer to Tom Hanks to Tom Brady, the name projects an everyman confidence. Simple, strong, and impossible to date.
