The Grand National Curling Club (GNCC), founded in 1867, was the first National Curling Organization encompassing the entire United States. It remained the national organization until it created the United States Curling Association (USCA) in the 1950s, which split the GNCC into 10 Regions to compete in a U.S. Men's National Curling Championship. The champion would represent the United States in the newly created Men's World Curling Championships.
