The 2006 Lamar Hunt U.S. Open Cup ran from June through September, 2006. The Chicago Fire won the championship, their fourth Open Cup title in nine years. The early rounds were most notable for the surprising run of amateur side Dallas Roma F.C. of the North Texas Premier Soccer Association. Roma barely survived the first round in a penalty shootout win over PDL side Laredo Heat before upsetting Miami FC of the USL First Division 1-0 in the second round.
