The 1951 National Challenge Cup was the 38th edition of the USSFA's annual open soccer championship. The German Hungarian S.C. from Eastern New York defeated the Pittsburgh Heidelberg in a two-leg final to win. The Heidelberg manager later filed a protest with the United States Soccer Football Association, specifically regarding the "inefficient and partial" officials.
