The 2021 National Amateur Cup was the 97th edition of the National Amateur Cup, a knockout cup competition open to amateur teams affiliated with the United States Adult Soccer Association (USASA). This is the third edition of the tournament to award its champion a spot in the U.S. Open Cup.
Lansdowne Yonkers FC won their second National Amateur Cup title, defeating Cal FC 2–1 in the final.
Format
All four regions of the USASA will hold tournaments to crown champions, which would then qualify for the final tournament. Qualification for these regionals was determined individually. The final four teams then compete in a single location knockout tournament to determine a national champion, with an additional game in place to crown both third and fourth place.
Region I
Eight associations in USASA Region I sent representatives to the tournament for the Fritz Marth Amateur Cup. Due to the 2020 tournament's cancelation, five associations elected to send both their 2020 and 2021 amateur cup champions increasing the field to 13 teams.
The final of the regional tournament took place on June 19 at the Ukrainian American Sports Center in North Wales, Pennsylvania.
