A delegate is a person selected to represent a group of people in some political assembly of the United States.

There are various types of delegates elected to different political bodies. In the United States Congress delegates are elected to represent the interests of a United States territory and its citizens or nationals. In addition, certain US states are governed by a House of Delegates or another parliamentary assembly whose members are known as elected delegates.

Prior to a United States presidential election, the major political parties select delegates from the various state parties for a presidential nominating convention, often by either primary elections or party caucuses.
