2007 U.S. Open Cup
The 2007 Lamar Hunt U.S. Open Cup was the 94th edition of the USSF's annual national soccer championship, running from June through early October.
The New England Revolution defeated FC Dallas 3–2 in the final played at Pizza Hut Park, Frisco, Texas.
Pairings for the competition were announced on Tuesday, May 29, 2007. The 2007 tournament was the first since 2002 to not include all Major League Soccer teams. Instead, MLS had eight teams in the tournament; six qualified automatically, while the remaining six US-based sides participated in a playoff for the final two positions. In another change for the tournament, all nine US-based USL First Division teams entered into the Cup. The Puerto Rico Islanders are not eligible for the tournament, as Puerto Rico has a soccer federation independent from US Soccer.
