2018 U.S. Open Cup qualification
The 2018 Lamar Hunt U.S. Open Cup tournament proper will feature teams from all five tiers of the men's American soccer pyramid. A record 108 open division amateur teams have entered qualifying this year.
US Soccer oversaw the qualifying process that was formerly handled by each association. All teams within the Division I and II professional leagues qualified automatically as in past years. Any open division national league could use its previous year's league standings as its qualification method. Remaining open division teams participated in qualifying rounds to determine entrants into the tournament proper. Final slot allocation was determined when team registration concluded.
