The 2011 Lamar Hunt U.S. Open Cup was the 98th edition of the USSF's annual national soccer championship, running from June through early October.
Louis Central Breweries from 1933 to 1935 and Greek American AA from 1967 to 1969 — this excludes the run of Fall River F.C.
Like the previous edition, the Open Cup featured 40 clubs from across the five tiers of the American soccer pyramid.
This season, due to late provisional sanctioning, the North American Soccer League was not allowed to send its clubs to the tournament.
