The
Lamar Hunt U.S. Open Cup, commonly known as the
U.S. Open Cup (
USOC), is a knockout cup competition in men's soccer in the United States of America. It is the country's oldest ongoing national soccer competition.
The competition was first held during the 1913â1914 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 and dedicated to North American Soccer League (NASL) and Major League Soccer (MLS) executive Lamar Hunt by the United States Soccer Federation in 1999.
