Tony is a boy's name of Latin origin, first uttered as Antonius. Associated with the famous Mark Antony—great lover of Cleopatra—Tony's meaning is thought to be "priceless one." It's a name that will no doubt garner favor from many, reminding baby of their unquestionable worth. For others, Tony sparks a measure of menace or, at the very least, quiet authority fueled by the fictional antiheroes that bear the title.
