The general marriage age (lacking authorization for an exception) is 18 years of age in all states except Nebraska, where the general marriage age is 19, and Mississippi, where the general marriage age is 21.
This age is set by each state and territory, either by statute or where the common law applies. The marriage age in the United States is the minimum age at which a person can marry in the United States as a right, or with parental consent or other authorization.
