The Professional Referee Organization (PRO) is the organization responsible for managing the referee and assistant referee program in professional soccer leagues in the United States and Canada, working alongside the U.S. Soccer Federation, Major League Soccer, Canadian Soccer Association, the North American Soccer League, United Soccer League, and the Lamar Hunt U.S. Open Cup.
The organization's targets are to increase the quality of officiating in U.S. and Canadian professional leagues, develop more professional-quality officials at a younger age, and produce officials who will represent the United States and Canada in FIFA competitions.
