The 2002 U.S. Open Cup was the 89th edition of the Lamar Hunt U.S. Open Cup was a club soccer tournament in the United States open to all men's teams in the country. It was organized by the United States Soccer Federation (USSF) and featured 32 teams. The tournament ran from June to October. The Columbus Crew won the Open Cup with a 1–0 victory over the defending-champion Los Angeles Galaxy in the final at Columbus Crew Stadium. Just three days before, Los Angeles had won MLS Cup 2002; Columbus was the MLS Supporters' Shield champion. Every third-round game featured an MLS team against an A-League squad. Although the MLS teams won seven of the eight games, four went to overtime, including San Jose's memorable 4–3 win over Seattle. The Des Moines Menace turned in the best performance by a PDL team, taking Rochester to overtime in a 3-2 second-round loss.
