The National Building Trades Council (NBTC) was an American federation of labor unions in the construction industry. It was active from 1897 to 1903. The organization's primary goal was to provide a forum in which jurisdictional conflicts between trade unions could be adjudicated. But as a voluntary federation, the organization lacked the power to enforce its rulings. Many national and international construction industry unions refused to join the NBTC, further limiting its influence.
