Pretty much nowhere in the US. Offhand I can't think of any state that allows those under the age of 18 to marry without parental consent, with two notable exceptions: In some states minors are allowed to marry despite not having parental consent if the female half of the couple is pregnant, and in some states a judge is allowed to give consent in lieu of parental consent (though in practice this tends to boil down to essentially the same thing, as a judge is unlikely to override parental authority without an extremely compelling reason, such as pregnancy).
