List of United States national amateur boxing welterweight champions

Below is a list of National Amateur Boxing Welterweight Champions, also known as United States Amateur Champions, along with the state or region which they represented. The United States National Boxing Championships bestow the title of United States Amateur Champion on amateur boxers for winning the annual national amateur boxing tournament organized by USA Boxing, the national governing body for Olympic boxing and since 2023 is the United States' member organisation of World Boxing after leaving the Association Internationale de Boxe (AIBA) as a result of corruption scandals. It is one of four premier amateur boxing tournaments, the others being the National Golden Gloves Tournament, which crowns its own amateur welterweight champion, the Police Athletic League Tournament, and the United States Armed Forces Tournament, all sending champions to the US Olympic Trials. It was contested at 147lbs until 2002 when it was changed to 152lbs.
