1920–21 FA Cup qualifying rounds

The large number of clubs entering the tournament from lower down the English football league system meant that the competition started with an extra Preliminary and preliminary rounds prior to six qualifying rounds.

The five rounds from the extra preliminary to the third qualifying involved 430 teams from England and Wales.

These were arranged into 24 geographically based divisions which thereby created matches against local rival clubs and limited the travelling required.

Through a series of knock-out matches one team from each division progressed to the fourth qualifying round.
