Lamar Hunt U.S. Open Cup

The Lamar Hunt U.S. Open Cup, commonly known as the U.S. Open Cup, is a knock-out cup competition in American soccer. It is the oldest ongoing national soccer competition in the U.S. and the world's third-longest-running open soccer tournament. The 102nd edition, to be held in 2015, is expected to be contested by 91 clubs from the three professional leagues sanctioned by the United States Soccer Federation, including Major League Soccer, the North American Soccer League, and the United Soccer League, and amateur clubs in the earlier rounds of the tournament after qualifying through their leagues. The overall champion earn a total of $250,000 in prize money, while the runner-up receives $60,000 and the furthest-advancing team from each lower division league receive $15,000. In addition, the tournament winner qualifies for the group stage of the CONCACAF Champions League.

The competition was first held during the 1913–14 season as the National Challenge Cup, with Brooklyn Field Club winning a trophy donated by Thomas Dewar for the promotion of American soccer. It was renamed to the U.S. Open Cup in 1990 and then dedicated to MLS owner Lamar Hunt by the United States Soccer Federation in 1999.
